'In an effort to revamp the entire offensive line, the Bills declared that all starting positions would be up for grabs. It's really not that big of a stretch to think that the Bills don't have another option at left tackle besides Glenn, though. He'll likely resume his role as a starting left tackle, but the pressure is on him this year. He is a free agent as of March, and will need to show he can regain the form of his first two seasons before hitting the open market, or, to prove to the Bills that he should be re-signed when they have a bevy of other players on the roster to do the same with.'
