JC Jackson has the best passer rating allowed in the NFL

[PP2]

He needs to polish how he holds. He makes it too easy not to call. The best holder was Revis, he did it so well, if he wanted to turn his head while running, he will hold just a tad to make sure you are not turning or doing any funny movement, then immediately lift his hand once he gets an idea where the ball will be going. Revis should teach that tech, it will probably require someone with the same speed as him or better though.

He is getting there, this is only his second year. I've been seeing massive improvements.
