I assume Roberson has been getting meaningful snaps at qb in practice. Practice and mop up assignments have little pressure. It may well be that he lacks the emotional ability to perform in real game pressure. I wish him well in any case. He could not have responded worse than last night however. I give him major props for facing the press. It's a sign of maturity that was lacking in the game. I would not write him off yet. His worst is probably behind him.
