http://universaldraft.com/Bills_Blog.html Just a little look at how I think the Bills' draft choices will fare this year. I still think they will have issues along the offensive line due to all of the shuffling of their personnel. I would rather have Levitre at left tackle than Walker if it came down to it. I'd certainly give the rookie a crack at the job.
Not a Levitre fan, but Eric Wood will be a good offensive lineman for a long time for the Bills. Simply giving away a All Pro LT and All Pro G and not having anyone to replace them is insane.
