Who makes the decision on who plays in each game? Insert two competent players for #13 and #53 on D, which has been the case game after game despite the fanboys assertions on here, and the D would be strong enough to defeat both Vandy and USCe even with all the injuries. #13 nearly lost the UGA game as well. Yet, there both of them are game after game taking snaps that could be given to more talented players to gain experience. The results of the games would not be worse, only potentially better. Nearly every competent OC knew to isolate on those two. Those coaches know to look for winning match-ups.
I find the Debo question of competency fascinating as well. One should not use cumulative season stats to make the point. TN Tech goes in there. The basketball game against a bad Mizzou D is in there. The UK shootout is in there. All are bad D's. Each game has to be situationally analyzed. Debo presided over an O that was totally incompetent in 11 out of 24 halves of football. Not just underperforming - horrible. With one or more NFL RB's, 2 NFL WR's, 1 NFL TE, and a productive Sr. QB with 4 seasons of starting experience, and a couple of potential NFL O-linemen. If the bench guys cannot step up when injuries hit, especially the O-line, who else is to blame? Mahoney is a weak link, yet, Debo was touted as a strong O-line coach. I guess we know differently now. We know he's not a QB coach. We know he has been maddeningly inconsistent as a play caller. We know virtually no modifications were made in the O to accommodate player skill sets. We know he never fully took advantage of match-ups or Kamara, Malone, JJ and Wolf would have been used like crazy in every game in every half that was not already a blow out.
Maybe your definition of not being a problem is different than mine. Maybe 8-4 is your thing.
