re: Is the problem with defense personnel or coaching/scheme?

Well look. This defense wasn't EVERY gonna be good. You can't be "good" in college football with zero legit cover corners. The coach is forced to make too many concessions in how he plays defense just to avoid a bomb fest.

That said. Stuff like not even ensuring rushers stayed in their lanes against Alabama was asinine. Heck, Bama didn't even have to beat our DBs. If you're a coach in such a situation, you have to pick your poison. Get after the QB and hope the DBs don't get beat or, keep QB in pocket and zone like a MFer. Somehow we did the perfect blend of neither.
