He is faster and quicker. Jimmer has better handles. While Reddick is the better athlete, Jimmer has a few more things to work through. Jj Reddick struggled when he started out too. He had to change his game a bit and became a much better defender. In all fairness Jimmer has never been given enough time to show consistency. From what I have seen Jimmer looks to be improving but Keith smart and saCRAPmento didn't do him any favors. Also Jimmer is much better at penetration, better at finishing at the hoop and a better passer.
