I think he has the athletic ability and arm strength to be great in this league. I don't know about his head but I watched him lead the Browns to a win in Pitt last year that was very impressive. IF we could get a deal out of him like we did with Frerotte a few years ago, I would be totally in favor of that.
As for Brown.. he sounds interesting. Dude is a road grader and a mean one at that. It would be good from the standpoint that maybe he could tutor Foster in the attitude department. The thing is, can he play LT too?
