To all those saying he is too slow getting off the ball. How many are expert DC's to know what his assignment actually is? He is not pass rusher, so he needs to react to the run so he needs to read then react as to the direction of the play.
So is he really that slow, or is it just a thing against a player.
How many can really tell from watching him on a TV screen with the camera half way up the stadium when you see the entire offense and defense at the same time.
I will give him more time, it is his 2nd year, and he had no offseason work due to shoulder surgery.
