Reason for concerns: AFC East (SportingNews.com)
A capsule look at reasons for concern among teams in the AFC East: Buffalo Bills 1. Left tackle. The Bills might not be good enough at the position. LT Demetrius Bell struggled mightily last season and has gotten limited preseason reps coming off knee surgery, so stamina might be an issue. RT Cornell Green has not looked good in pass protection. The Bills must limit long-yardage situations because shaky pass protection could endanger QB Trent Edwards.
