I'm just floored at how they act like they invented some new complex scheme.
In the world today, especially with pass happy spread teams everyone has figured out that if you can get to the qb fast (have an attacking defense) you can get a team off schedule and behind the chains. Which is great, except when they counter that. Over pursuit and getting up field to fast can leave lanes open. Which is especially bad with a qb who can/will run. That's why you see so many college teams playing mobile qb's, because if you over persue and leave a gap open, they tuck and run. It's a way to counter attacking defenses.
Phil has done a wonderful job of teaching a balanced and proper defense for the modem era as shown by the total defensive rankings.
I know everyone is saying AJ should have had more snaps. He is extremely talented but he is also young. No doubt if he stays and keeps learning as much as he can for as long as he can, he is going to punch his own ticket. I know to fans, we want to see ________ but sometimes there is more going on there. Few of us doubt AJ couldn't "beat" just about anyone you line up across from him, but the question is can he maintain and shed. Bring it when called upon. Remember if you first drive your blocker back before shedding, you have created even more traffic in the backfield, not to mention will get numerous block in the back/holding penalties. I recall last year's Nebraska game and there was definitely some over pursuit going on. I'm glad that qb was a freshman. We were getting back there but several times couldn't get hands on him in the beginning of the game.
Anyway back to this 3-4 the whole concept is based on having a ng that has to be double teamed. But you only have to do it for a second, like a chip and then move on to the Ilb, if you have a rb who is hard to bring down, there is yads to be had right up the middle. The more tired the middle gets???
Other than that just remember most of the attacking from a 3-4 comes off the edges (which leaves less coverage). Sending an Ilb up a gap (if the ng can command a double team) is a much riskier play. They will do it but the interior of the ol, (or rb in pass protect) that is double teaming a ng just has to be aware and heads up to gap control and drop the double and fill the gap if a Ilb tries that.
There. Simple and to the point. I just destroyed his million word argument in a couple of paragraphs.
