Going to need strong d-line play again. The edge is going to be the difference between a top 3 defense and a top 10 defense. The BIG defenses are pretty insane this year, with OSU being a solid #1, Iowa being a very close 2nd.
Black, graves, craig, should give you confidence. Allen could be a breakout guy, with graves possibly being the stud and figure nfl pick. Depth looks decent, but if we lose a DT will get sketchy
