I think Opie McMiddlefinger was a liability for them last year, but not entirely for his play. The boy was too full of himself. He was always erratic when pressure was applied; all you had to do is pop him once and the offense went to shit.
After the Duke game, when the fluff articles began to flood the papers and BSPN about him being a "field general" and "game manager" - rather than an above adequate quarterback, it became apparent that he allowed it to go to his head. He became too cocky and arrogant and, to me, it showed in his performance. Don't get me wrong, a cocky QB can be a very good thing, but arrogance will kill a team quicker than anything.
With the weapons the updykes had last season, all this dunderhead had to do is hand it off to either the fast or to the furious or chunk it up to Juicio or Hanks, and they're looking at their second straight undefeated season. Instead, he tried too hard to be that mythical monster the media tried to make of him and he fell flat on his ass and took the team down with him.
