He came in with the attitude of not wanting to play OLB and not wanting to reduce his weight after bulking up to be a 4-3 DE. Limiting his responsibilities to DE (fewer keys, no pass coverage) and not fighting his attitude probably would have helped. Not enough to make him Richard Dent, but at least better than the Arthur Dent the Packers got his first year.
I've not heard anything negative about Randall's attitude at all. Questions are can he learn the position fast enough and can he overcome the size difference against some of the taller receivers.
