Please forgive me if I'm wrong. I was under the impression that the Bama 3-4 was primarily the more aggressive 1-gap specifically because getting the personnel necessary to run 2-gap (even at Bama) is too difficult at the collegiate level. They do, however, run more aggressive corner back schemes that take advantage of superior athleticism. Again, I may be mistaken, but that was how I understood it.
I do agree with the rest of your point. We MUST run a scheme that maximizes our potential and strengths. That is what I think the great coaches are capable of, and what I hope we are capable of.
I believe having two legitimate threats on the inside will open up our defense. It's incredible how one additional playmaker on the inside can make the rest of the defense look better. This is on top of the fact that our back four may be the best we've seen in some time already.
bama plays a ton of 2gap too...sure like any D they can call aggressive sets...but they rush 4 alot and just man up and beat you so they don't expose the backend to same way we would have to run alot of cover 3 shell...bama is in 2 deep man alot...when they had that huge DT Mount Mckinnley or whoever...they 2gapped alot
