Interesting points re Greg Robinson. I can't help thinking Anthony is right even bearing in mind Greg's age, experience at the LT position in the NFL and the system he came from.
He may be raw but he's a physical beast yet he doesn't use that enough. You have to assume it's a mental thing and question whether he's ever going to get to be a league average LT never mind end up as a very good/elite 10 year starter.
