Look at the teams he had good games against. It was some of the worst secondaries in the league.
Now, he also had some good games against good teams and he didn't have much around him. So i tend to give him a pass on some of that.
But he had alot of questions about his accuracy coming out and was supposedly really innacurate in the evaluation process.
He showed last year that he isn't awful in that area, but he also wasn't consistent.
