Concerns? Yeah just a few:
1) Fitz. Looks like the same QB we saw the second half of last season. Inaccurate, confused by a 3-4 D, flustered when pressured. The difference between Fitz and a great QB like Big Ben is stark.
2) Our vaulted D line was simply not a factor on the last drive of the half. Wannstache was schooled by LeBeau.
3) Aaron Williams is not the answer at corner. Speed receivers will eat him alive.
4) Oline better learn to handle a blitz or Vince Young will be playing a plenty.
