If he makes the team, hopefully he can be a boost for us in short yardage and GL running. We know he can catch and he's really good in blitz/pass protection, but if he's relied on to be anything other than a rotation guy all it does is hurt the production of the offense.
He wasn't overly productive last yr on a terrible football team, but I do remember watching that late season game at Pittsburgh and he basically won the game for them. He carried 22 times that night and had another 7 receptions for 72 yards. He also made the play of the game when he ran down a Pats D guy who had picked off a pass for what looked like a sure TD. He did that for a 1 win Pats team (at that time) against a Pitt team that had to win that game at home. The effort was still there even when their season (and possibly his career) was over.
