Too big for my britches

I keep getting hit with this Daily Bandwidth limit exceeded thing. Looks like I really ought to move the site to a better host and purchase a domain, though I really hate to move the site again. I still gets lots of traffic routed through the original nohuddle.freeservers.com address, and many of the old football sites simply do not update and won't be changing their lniks. I would sure hate to have potential link-clickers have to be re-route twice, but I'm out of good ideas.

There had been some talk of a name change too for the site. I'm all for any ideas you have.

Lastly, I've been wanting to solicit other coaches for articles for some time, but none have submitted any yet. I even approached a few upper level coaching staffs, but all were a bit wary. Maybe in time.

Anyway, just wanted to apologize to those who keep seeing the Daily bandwidth limit exceeded page. A surprising turn of events for a little site that has been around for several years (ironic though that more people check to see what I have to say now that I am no longer actively coaching, though I do have more time to update).

Substitutions, Personnel, and Formations

Anyone who has watched Edge NFL Matchup (the best football show on television by far) is familiar with the idea of "matchups" or "formationing". However, rarely is the concept used properly by coaches. Often, even experienced coaches will give lip service to "using multiple formations" and that, without purpose, if you run X number of plays in Y formations it somehow inherently makes you a better offense. Further, tactical substitution is even less understood. Sometimes not substituting is tactical (i.e. the wishbone or run and shoot looks the same pre-snap every play), but substitution and formationing are tools to be used by the crafty coach.

The great advantage to formations and substitution versus new plays and schemes as a tactic is that new schemes and plays require the coaches and players to learn something new. Whereas, on the whole, a formation, once learned, can be used over and over in many different situations, and a personnel grouping only requires that other players learn certain responsibilities (which can sometimes be demanding if that player is required to learn several significantly different positions). However, the coach can pretty much substitute or throw in a new formation at will, and the players pretty much will execute their task regardless of who is in the game or what the formation is.

Formationing

I will discuss this the least, since the literature and discussion of formationing is more widely available, and I think the most useful approach to this is for individual coaches to spend some time doodling it onto paper to see what can be discovered on their own.

However, this is the first tool used. Each defense has various strengths and weaknesses, and often defensive coaches, consciously or unconsciously, will often try to overcompensate for these weaknesses through personnel or tactics, so that creates further games. However, knowing these strengths and weaknesses is important for any offensive coach. For example two situations are digrammed:



On the left, the offense lines up in trips, which is troublesome for a defense that wants to play cover 2. The three frontside receivers require coverage from the undercoverage defenders, and the QB and RB can option or run the ball to either side, putting the inside linebackers in a bind. Further, with a favorable matchup, X versus the single cornerback presents different problems, particularly for slant routes. Thus the offense can kind of work a progression of frontside quick passes, strongside running to weakside running, to weakside passing, making the lives of the defenders, particularly those two inside backers, miserable.

In the diagram on the right, versus a 3 man front, vs what we would call a 3-4 strong stacked (or a 3-5 if the team uses this consistently as a base defense), we first line up in a balanced formation, seeing if the defense tries to load one side or another.

Most importantly though, with only 3 LOS defenders, we go two tight ends (we can go 2 backs and 2 tights if we truly want to be a powerful run team). First, we have six inside gaps (8 if you count off end runs) that the D must account for, and we can double team all of the LOS defenders and still have a free linemen, here the left guard, that can free release to block a second level defender. From here, as with the trips, the games would begin where we would want to run the ball, waiting until their contain defenders cheat inside or the free safety cheats up, at which time we would start throwing quick passes or passes off a run action.

Personnel and Substitutions

When planning for the year, it is important to identify your "studs" or the players that can change--and win--games on their talent, ability, and drive. These can take different forms, from gamebreakers to linemen who can pancake defensive linemen to a multitalented tight end or wingback, but they must be identified.

Second, you must flesh out your O with your best 11 players. I am a firm believer than you need a strong 11 players who are your "starters" and these will be the guys that help you score points and win games. I do not have guys that just stand out to the side or linemen we don't run behind, all are expected to contribute.

Starting from this helps discipline your thinking when substituting. Coming back to your studs and your best 11 helps prevent you from substituting without purpose or for purely cosmetic reasons; if I am going to take one of my best 11 off the field then I need a damn good reason.

The Value of Openers

First, when designing openers I like to, almost indiscriminantly, get the ball to some of my studs. As little as it should matter, psychologically it helps them get into the flow of the game, and they approach games more seriously and confidently knowing that we have plays designed for them to get the ball early when we practice our openers.

However, we also run lots of formations, motions, and a few substitution packages to get a feel for the defense. First, this can send them scrambling to see what we've thrown at them, but, most importantly, we want to see what they do. Do they put a linebacker or a safety on this guy? Do they shift their backers over? Do they shade their DL? Different coaches watch for these adjustments and we confirm a picture about the D. The more unconventional your offense the more important this is. From my experience teams would line up in all new defenses versus us almost every week, so our weekly preparation had to be contingency based rather than definitely prescriptive.

The big question we ask during the week and seek to confirm early in the game is: "Do they substitute based on situation (down and distance) or based on offensive substitution? Is there a breaking point where they shift between one or the other?"

This is very important, because it changes our entire method of substituting. If we know they like to go nickel on 3rd and 7, then we need to anticipate the nickel personnel and maybe we want to stay in base, or maybe we MUST sub in quicker players or else our RBs and tight ends will not get open. Conversely, if they substitute based on personnel, maybe we can do a power package on 1st and 10 and they will take out their free safety who we really fear in the passing game but is a poor tackler. This will be worked on all week as well as mid-game.

Again, the great advantage of this kind of strategy is it does not require the players to learn anything new. We do like our players to be smart (I used to tell them that by the time they leave I hoped they could all be coaches), but it doesn't require extra practice time to do this kind of stuff. A new trap play does.

Walkthrough of Situation

To help highlight what I mean, I will walk through one simple situation. Let's say we are a base pro-set team, with a halfback, fullback, tight end, split end and flanker. W want to make an adjustment and line up with the halfback split out as a receiver, so we move him outside of the split end and we look to see how the defense adjusts, as diagrammed below.



First, do they cover him at all? If they play way off, we may want to throw an immediate pass to H, who is our best runner, out in space. I've called this, seen our halfback make some people miss and score a long TD. Makes you feel like a genius, but is so obvious!



Here, they play man or some kind of "up" coverage. Importantly, since the cornerback's rule is probably something along the lines of "take the widest man" then our split end, our best or second-best receiver and route runner, is now matched up with a linebacker (it could also be a safety, and this could be advantageous as well).

Let's just say that it is pleasing to look up and see one of your speedy guys being covered by someone with their number in the 50s (or up!).

Obviously here we would try to isolate our split end on this player and let him beat his man on a pass route.

In the diagrams below the defense matches up with the corner on the split end and moves the LB out. Aside from the passing game, this is helpful for the run game, as we have taken a better run defender outside. Anyway, though, we now have H matched up on the outside with a LB.



Above we show the RB versus this backer in the backfield or split out. While he can run many routes from the backfield, he is not the threat deep that he would be, and the LB has more help from his safety and other cover man inside. However, split out on the sideline, he is on an island, and must first defend against the straight go or fade route (also the easiest to teach a RB who otherwise needs to learn other responsibilities).



Lastly, if we have been successful with all of these tactics the defense may get fed up and rotate a zone over to this side. First, we realize that we still have a strong run formation strong with our tight end. Second, it is a 3 receiver side, and we can flood the zone to this side where we can achieve an advantage. Thus are the cat and mouse games of offense vs. defense.

Motion and Shifting

I will be brief here, but motioning and shifting are easily applied to the concepts shown in this article.

The first thing about motioning or shifting is that they achieve the same purposes as formationing and substitution--it is the final formation that truly matters--but they generally give the defense less time to adjust and see what you are doing.

Motion

There is lots of overlap between motioning and formationing, but here is a brief list of reasons to motion (mostly taken from Bill Walsh).

1. Create a certain mismatch
2. Force the defense into a certain coverage
3. Put a player in best position to do a job (i.e. motion a RB out to go deep)
4. Confuse the defense's responsibilities
5. Disguise the play by breaking a formation tendency
6. Give them more to think about (motion causes emotion!)
7. Force defense into revealing keys (can be misleading at times)

Do NOT use motion cosmetically. If you are just motioning to motion, because you think you should, then you are wasting time and throwing off your offensive rhythm. You are better off getting to the line and calling the play on a quick count.

The special case of orbit motion or return motion, where a player motions in, usually to the center, and then goes back out to where he was, is on its way out. At one time this was very effective for determining if the defense was in man or zone, but has become increasingly less telling, and you see it less and less at the higher levels of football. If you see value in this motion then by all means use it, but its usefulness is decreasing.

Shifting

Shifting, as compared with motion has a few strengths and weaknesses. First, its strengths are that more than one player can shift at a time, and, as shown below, you can actually change the strength of a formation (which can be done with motion but not as easily or dramatically). This is maybe the most powerful adjustment at the LOS you can make.



The primary weakness of a shift is that your players must be set before the snap, giving the defense some time to adjust, while motion allows less.

Conclusion

This is the probing approach to formationing and personnel. It is not reactive in the passive sense. "Take what the defense gives you" has been changed from useful advice to a condemnation of conservative playcalling.

However, to some extent, it is still true when approaching the game tactically. This is formationing, shifting, and substituting with a purpose: intelligent strategy incorporates what the other team is doing, while staying true to your team's strengths.

Moreover, football is still a game of talent and people. If their 11 are better than yours, it probably matters little whether H is in the backfield or lined up wide as a receiver or if you shift your tight end from one side to the other. However, you look for what you can get. If you can find one personnel advantage then you can potentially trigger a structural change that can open up the rest of your offense and put your other players in position to succeed and contribute.

During a game you may have 2, 3, or 4 of these little mini-games going on. Moving this guy here, motioning that guy there, recreating the formation and doing something different, etc. A well designed and well taught offense can do these without confusing your players, putting the D in a bind. Conversely, a well designed and well taught defense can react to all these little offensive tactics and still let their players just go out there, play some football, and hit somebody.

To reiterate a running theme, football is a very simple game. The actual concepts you use, the number of ways to put 11 (or 22) pieces on the field is more finite than we think. All we can do is to teach our players as best we can during the weeks and then on gameday put them in the best position to succeed.

Number of plays

Coach Bill Mountjoy had a clinic a few weeks back (which I was unable to attend, but I heard was amazing).

From the early reports Larry Zierlein, formerly of the Cleveland Browns, gave a talk heavily based in empirical work about several topics concerning the run game in the NFL, but particularly about the number of run plays used by the best rushing teams. As reported to me (something like 3rd hand, so forgive me if I miss some details), is that there is an optimum number of base run plays for a football team, and, surprisingly, this ended up being only around 5 run plays--at the NFL level!

I'll have to wait for the actual numbers, but this makes intuitive sense, and can be applied to much of your offense.

First, how many times do you run the ball? The typical NFL team runs it around 25 times a game, so that is around 5 times a game for a run play to be run per game. High School games are shorter, D-1 football games are longer, and, along with how many times you run the football, the number of plays can be adjusted from there. The kiss of death is to have a "base" run play that doesn't even get run in a football game, even worse is to have several football games where it doesn't get called. This is a good sign it should NOT be in your playbook.

Implicit in these reported success rates is the amount of practice time dedicated to each play and its techniques, and how comfortable the players are with it. If the best rushing NFL teams only have around 5 base run plays, why do you have 8 or 9? They are dealing with players much more versed with the fundamentals of running the football (blocking, running, eyes up, even handoffs) which you could be teaching instead of adding new plays, have more time, face more variations in their fronts, and, sorry to say, are probably better coaches than you or I, as well.

Furthermore, let us say that you have identified a weakness in your opponent and you want to run the ball off-tackle. You have four off-tackle runs. What is the likelihood that you will call the right one? What is the likelihood that your players are comfortable with all four of them versus whatever front you see? Having extra plays makes your job and their job that much harder, without making your opponent any weaker.

This mindset applies not only to run plays. While we can dream up a multitude of passing scenarios, football is a pretty simple game in terms of what one team or another can do, and much of it is simply window dressing. Therefore, you probably need many fewer pass plays than you would like to have in a perfect world. The same logic used earlier applies to passing: if I have a play or two that can defeat a particular coverage, how many more do I need? It may even look dramatically different than the other plays that attack that coverage, but is it really a necessary tool? Especially compared to what else I could be practicing?

Up to this point I've focused mainly on "base" plays, i.e. plays that make up the large chunk of your offense. There are certain plays that only need to be called once in a game to be successful, or are necessary for certain situations and are crucial to help you win, but you may not actually experience that scenario. Examples are some play action passes, trick plays, goal line plays, and fake punt/field goal plays. These justify practice even though you may only call them a few times a season.

However, the same rules apply: how many of these do I need? Do I need 6 goal line/short yardage passes if I realistically only call a few all season? Do I really need so many trick plays if I only call one trick play per game--if that?

All this speaks to paring down your offense (and defense) as much as possible. This is not always so easy; we see the gains of adding a new pass play and scoring a touchdown or getting a particular first down more visibly than we see our general effectiveness at the rest of our passing game deteriorate from lost practice time. However, this is exactly what Larry Zierlein's empirical results showed with the running game in the NFL.

Further, it is sometimes difficult when comparing plays. For example can we really compare the inside zone or triple option with a quick trap? The zone and the option require significant practice time outlays, and are more adaptable to more scenarios. However, we could install the trap, and a fake trap with a boot pass, and a third counter in the same practice time. Which is better? One is three plays, the other only one?

This is why being a coach, despite the fact that football is simpler than we usually make it, can be quite challenging.

Sprintout/Half-roll passing

Discussion of half-roll protection and diagram from my original website:



Our half-roll protection is very similar to that used by the run and shoot, except our QBs have more freedom to keep rolling out. It is actually designed as a full-sprint out, but the QBs usually end up stopping and setting up after a half or semi-roll out.

It has been a great benefit to vary the launch points for our QB. I am a firm believer in dropback passing, but a simple way to roll-out has been very effective. Further, this has helped a diverse number of QBs, particularly shorter QBs and ones without strong arms. I think many QBs can be more comfortable with the rollout and half-roll passing game.

The Rules:

Backside Tackle: Backside Tackle: Turn and Hinge
Backside Guard: Turn and Hinge
Center: If covered or shade to callside, reach. If uncovered with no shade to callside, turn and hinge.
(Note, on turn and hinges, unless you make immediate contact begin to get depth to stay between the QB and your man. You do not want to be still on the LOS as the DE comes upfield)
Playside Guard: Reach, plug hole/backside
Playside Tackle: Reach (Note: On any reach block, if you are unable to reach, ride your man out to the sideline. Don't get beat outside trying to reach hopelessly. A man pushed out of bounds and kept on the LOS is just as effective.)

RB: Take two steps to callside, looking at outside rusher. Look for OLB or outside rusher to come shooting, block first color that shows. If none show, check middle and then backside. You are the QB's bodyguard. Step to rush, do not wait for him to get to the QB.

QB:Pre-snap look is key. QB will go at a 45 degree angle to a depth of 5-6 yards and then will level off. He will need to get his eyes up, and look downfield. He can continue moving parrallel to the LOS, but he must know when he must stop and step up in the pocket and deliver the ball. If he breaks contain he can continue out, he does not have a set place he has to be, but he must be smart.

This is a protection reliant on the QB being smart. On a dropback everyone knows he should be in the pocket, 5-7 yards behind the center. In this protection his blockers are doing the best they can and he needs to find the best space to throw or run the football from.

He must help his blockers by not getting into trouble and thinking he can outrun everyone. He must have a good sense of timing and be well practiced, as this type of dropback is not as carefully calibrated as our 5 and 3 step drops are. However, its simplicity has been a real asset to us.


Below are some of my favorite sprint out/half-roll pass routes and a (very) brief discussion of each. I like to keep them simple. Also, this series becomes even more viable in the red zone, where giving your QB a run-pass option can be a huge boost to your O. Also, most of the passes are designed to go to the outside, since a) one advantage of moving the pocket is making these passes shorter, b) it puts the defenders in a tougher run/pass bind and c) throwing on the run is easier when the receivers are either stationary or moving in the same direction as you are, so we try to limit receivers to these two categories.



1: My favorite movement pass. The outside man runs a post-curl, looking to make his post move at 8-10 and then curling at 13-15, depending how upfield the defenders are. #2 wants to run a 10 yard out. I like to speed cut this out, but some good passing teams prefer a sharp cut. The QB reads outside to in. He wants to throw the out route every time, but if they fly out he will point his shoulders inside and throw the post-curl. If the post-curl isn't there he thinks run, looking to cut back against the grain. I've seen more than a few long-TD runs by QBs on rollouts, almost all cut-back runs.

2. My second favorite. #1 runs a whip. He will release inside and push to 6 yards and turn back to the QB. Versus man he will pivot and run back to the sideline, versus zone he will turn back to the QB and slide with him. #2 runs a 10-12 yard corner. The QB reads corner to whip, again looking to run/cutback if they are not there. Great in the red-zone.

Also, you can run this from trips sending a man on a seam route (#3) or a go route down the sideline (#1). Either can hurt the defense, but the go is the easier throw for the QB.

3. Great sideline route. Outside receiver runs a comeback to the sideline, making his break at 15. The slot pushes to 12-14, turning inside to the QB but pivoting back outside. Again, the QB reads outside to in.

4. This is a simplified version of the run and shoot choice route, diagrammed in 6. You can tag or call the single receiver's routes, and then from there read across the field as the receivers come into the QBs view. Some coaches would prefer to read deep to short for the deep cross and shallow cross/drag, and while this would be desirable, the receivers come into the QB's vision in this order and this will better reflect how the defenders will actually react to the receivers.

5. This is our adjustment to the first play I diagrammed. Here, the slot runs an out and up and the post-curl looks to whip back out to the sideline a bit more. Great if if you've thrown this a few times and the deep cover men (safeties/corners) think they can jump your possession passes.

6. The run and shoot choice route, thrown in just because it is so effective. Most of you won't want to install all the reads (I didn't), but it's a play many teams have had great success with.
