He needs to figure out an answer for man coverage. Against a zone, he has had alot of success, partly because hes better at waiting and then zipping it in there when the receiver is open.
I dont know if the problem against man coverage is him, the receivers not getting separation, or the play calling.
But after yesterday's game where he lit up their zone, it's even more of a reason to figure it out because this week we have a good Denver secondary and New England who has more than likely noticed that we have struggled vs man coverage.
That's just my opinion, and I dont have any advanced stats to back it up.
