What I'm really seeing from this D is that we are jack of all trades master of none.
Our front is asked to do so many different things, that they don't excel at any of them. I heard people constantly say "I want to see an attacking DL"...."play single gap".
But when we do exactly that, we don't execute. We are slow to get off, and don't exhibit any speed.
When we play two gap, we mostly just create a wall right in front of the pocket, but we leave massive cut back lanes and no passrush.
I get that NFL teams do both, but honestly only the very best ones do, and those who do usually do it with sub packages on third and long.
Constantly switching fronts down after down is just not something I understand anymore.
Take that Duke big run. What you see there is a 4-3 under, it's really a 2 gap 3-4. And what you have is every DL crashing, leaving an OLB on an island with the TE. McCord is so concerned with contain that he allows a massive cutback lane. But bc we are in a 4-3, it's not an ILB asked to fill, but a freaking flat footed CB who stands zero chance.
Now we can say "well they had a guy to make the play", but it's a nonsensicle way of defending the run.
Want to play 2gap? Run a 3-4, keep it simple. Want to play single gap? Stop wasting precious practice time on 2gap principles and get guys to get up field! These aren't professionals.
So what is the difference between a 4-3 under and a 3-4 under? Teams still treat it as an odd front 3-5-1-5-9. They haven't wasted time teaching 2 gap because the film shows flashes of what they are teaching. Ther issue is not the scheme it's the talent. Let's be real here, if Miami lined up in a 4-3 front trying to play 1 gap Curtis porter would be the only guy in the backfield. Chances are that only happens 2 games a year considering his injury report. below are a few clips of what is being taught being applied in games. Olsen Pierre is on most of these clips and he is making plays not because of his explosiveness but because of technique. Corey King actually makes a play in the spring game early on by crossing Wheeler's face when he attempts to block back on power on the first drive I believe. (I don't have a link for the spring game yet.)
