they need to take the tackle from standford if he is still there or even matt kahil if he is still there for some reason. i dont think bell is going to come back and harriston did decent last year but the bills need a sure thing at left tackle and that is one position that hurt them last year. levitrie is more of a guard so he cant really move out, only if there are injuries he should move out there other than that him and wood will lock down the middle of the o-line and we got a decent right tackle now all they need to do is sure up that left tackle spot and the o-line will be fine. if it comes down to it they need to take quition coaples from north carolina.
