I give him a B:
Why not an A? A few mistakes (judgement) on interceptions, although 2 of his INTs were batted balls and not entirely his fault. Also, he seems to miss Cooley a lot when he's WIDE OPEN in the middle of the field.
He has a cannon for an arm and runs for first downs when he doesn't have a throw. He runs like a RB too, a big powerful RB...breaking tackles, using stiffarms.
