33 thanks for being specific.
It would help if in 17 could u watch replay while statistically noting for 3rd down some info relative to down distance , yard line offset of db, safety , fl at foot , back pedal, blitz lanes results.
I hope we are doing simple stuff like camo the coverage (8 on line then shift do and drop into coverage or blitz. That will be obvious to even untrained db eye (me).
If u get data u could detect change or not and make your presentation on gt swarm really meaning full. Engel love numbers.
By way my son who coaches hs in east texas says there is a online service that does the games breakdown and provides some level of down distance tendencies.
Thanks
I did this last year. I did a down and distance, situation, and the type of d we played with the results game by game. LOL. It took a while.
I then published success precentages on third down etc and the success of the offense.
What I found was we essentially play alot of 1/4 1/4 1/2 coverage. Which, some quarters DC feel is the right backend for todays spreads and zone reads. Its a version of quarters. In general, quarters is regarded as a more prevent call. The statistics showed we were actually the worst last year giving up chunk plays in this coverage than any other. It could be because we were in it more often (obvious), but what I noticed is we tend not to mix up pressure packages with this backend; and when the 1/4 and 1/2 S bailed in coverage (back pedal vs stand ground) we left open massive passing windows.
Blitzing in 1/4 1/4 1/2 was not often. It did happen, but not enough. So, as an opposing coach...its easy for me. On 3rd down, when I see this coverage, or 2nd down, Roof has all sorts of tells; first, my line and RB checks are to the MLB. If we blitz; its him. But, we rarely do. So my OL and RB really are not too concerned....Now my QB is relatively comfortable knowing the chances of blitz are low. We line up in our coverage presnap, its super easy to diagnose. So I probably already know where I am going with the ball at snap. If 1 is covered I go to 2.
We did, also not often, disguise a cover 3 with a 1/4/1/41/2 presnap roll a few times. Again, not often. But we would drop the 1/4 S down and roll the half S to the middle of the field at snap or tried to just before snap. The problem with doing this, is the weakness of the 1/4 1/4 1/2 scheme is the same weakness with the cover 3 LOL. Its the dumbest roll in all of football. Weakness of a cover 3 is a curl in, flats and digs....well what are the weaknesses of quarters. Flats, post/flags, and curls. So, basically, if a QB reads quarters, and we roll to cover 3 and he is presnap reading to go to an inside slant, or curl...he is right every time. If he presnap reads to attack the D with #2 on playaction, he is right again, every time.
Quarters by nature is a strong run defense look. but has a HUGE weakness in play action covering 2. If 1 runs a 9, and #2 S reads his key on run, and its playaction, and he is wrong....#2 is wide the hell open. Sound familiar? As a result, in flood concepts, scissor concepts etc, there are ALOT of checks between the S and CB to make up fo this big weakness in D. There are anywhere from 4-6 checks in quarters presnap to get your coverage and communication right. Especially in trips; where the CB has to take the presnap S man, and the S has to come up and take the CB man.
This is why Roof is simplifying. By nature what he runs requires many many checks to prevent the weaknesses in cover 4.
Now, my view is this. Cover 4 is tailored to stopping the run game. Done right, it SHOULD be harder to run on cover4 teams. Simply its easier to drop the S down quick for run support.
But, teams now, basically pass more. We see many RPOs which eats up quarters. We have 3 WR sets that are base now. IMO we haven't switched.
In coaches clinics they are really talking more and more about half field man concepts to the RB side for RPO. Man has to enter into the equation more now. But, you can get exposed in the run game, so they are doing partial field man concepts on 1st down. With half field zone shells. TCU really does this awesome. IMO we run enough man. We don't need to run more man. I do think we need to move from 50%+ in quarters, to more cover 3 and cover 2; and mix in half field zones. We need to change our S drops. And finally we need to make sure if we roll coverages, you show a coverage with a weakness, and roll to a coverage where its a strength...not to another coverage that shares many of the same weaknesses.
