The defense. Some good games (FSU, Miami, KU), some decent games (OU, CSU, Baylor, TT, Bama) some clunkers (KSU, NU, Mizzou, ISU, ASU). -They were wildly inconsistent all year. The losses of Wheatley and Dizon are huge, and those are gigantic shoes to fill. The Buffs need to have a DE breakout and become a pass rushing force. Imagine how much better this D would have been with an Abe Wright coming off the edge this year. Hopefully Lucas can finally put it all together (not holding my breath) or perhaps one of the young bucks (Obi, Herrod, Perri, Hudgins) can step it up. -An offensive Identity. Not a smash mouth team, not a spread O, not a run and shoot, not a WCO. We saw lots of spread looks in the bowl game, but the results were suspect. Losing Charles is a bigger deal than most are willing to admit, and until PT Gates and Darrell Scott are actually on campus, we have a gaping hole at RB. Maybe it was all the youth on O that contributed to what I perceive as a lack of identity and hopefully that's cured in Spring Ball. A couple of the RS frosh are going to have to step up to replace Polumbus and Harrison.
