You'd have to be blind to not think he has problems with accuracy. He has gotten a lot better about his decision making the latter half of the year, but as far as accuracy.....there is room for improvement to say the least.
I think consistency is his problem. He can make every throw, and be as accurate as any one in the league. Now, when he does it 60 - 70 percent of the time... then he'll truly be elite.
