I was reading a little about him. Supposedly his run blocking was ok Sunday, especially as the game went on. We(ok, me) were mocking him a little for getting whipped on that sack. Apparently the reason given that Morgan has a weakness with his drop step
Not being deep enough to handle speed rushers. The thought of the writer was that if he can get himself stronger and improve his initial drop step he has the talent to be a left tackle starter.

I don’t think they will resign Wallace. But I could see a left tackle competition at LT between Murphy and someone not on the roster now.
