Bills: One big question

Did the Buffalo Bills fix holes on offense?

The Buffalo Bills, who finished 6-10 and last in the AFC East, get a solid "A" for their offseason acquisitions in free agency and their selections in the draft. General manager Buddy Nix made very aggressive moves to get the team in position to make a run in 2012.

But did the Bills, my sleeper pick for 2012, do enough to plug their holes on offense? Buffalo invested a majority of its free-agent dollars on defensive ends Mario Williams and Mark Anderson. The team also used its first-round pick on cornerback Stephon Gilmore. But the Bills didn't start to address the offense until the second round.

Buffalo's biggest offseason holes on offense were at left tackle and wide receiver. The Bills used their second-round pick on offensive tackle Cordy Glenn and their third-round pick on receiver T.J. Graham. Buffalo hopes both rookies can fill these important positions in Week 1.

Glenn is a solid prospect, but there are questions whether he can handle playing left tackle in the NFL. He split time at guard and tackle at Georgia. That helps in terms of versatility, but the Bills hope Glenn can fill the open left tackle spot full time.

Graham has a chance to compete for the No. 2 receiver position opposite Steve Johnson. Graham does not have prototypical NFL size (5-foot-11), but he does have very good speed to blow the top off the defense. A deep threat is something Buffalo's offense lacks. Graham will have a chance to compete with David Nelson and Donald Jones to be the No. 2 receiver. Nelson is more suited to the slot, and Jones has durability questions. Can Graham, a third-round pick, beat out a pair of veterans?
