In the ravens game he had just come back from injury. I'm sure he was probably still playing hurt and there is no way he was in game shape- after missing like 9 games. I don't fault him for the ravens game.
I'd love to see him take Beadles job at LG. kuper is better at run blocking and pass blocking IMO. He may not be as good at pulling I am not sure. Beadles is pretty good at pulling. But a camp battle would only benefit the team.
