Simple. We are losing a lot of talent- Barnett, Kamara, Sutton, a senior QB that has started a ton of games- and leads the SEC- and these guys are difference makers. For a couple, that's an understatement.
A lot of people like to give passes because of injuries has made our defense look like crap. Ok, fair point, but the defense we've been left with is largely your two deep next year. Sure, some guys will improve, but probably not at the rate necessary to get to an above average defense. Besides, isn't the ability of the staff to develop players in question?
The QB situation should speak for itself. There are no givens how a QB will do in live action, and that's not even taking into account which QB choice the staff will make. We don't even have a QB coach! (I know, Sheridan). I can see a Mark Levine over Jamal Lewis type situation there for the first part of the season.
We will be thin in a few key areas- DT, CB, And RB. Injuries may be harder to overcome next year.
But hey, JG y'all.
