Redick will, and should, be a lottery pick. He might be a top 5 pick if things break right.
JJ's game has come a LONG way this year. Last year, calling him a quicker Kyle Korver may have been accurate. Now, it's an insult. Redick's defense will never be outstanding, but he's working much harder on D and ambushing the passing lanes more. Also, Redick is doing a nice job of hitting teammates and his conditioning is superb. Finally, he's no longer afraid to take it to the rack, which is doubly important, since he's such a great free throw shooter.
Why do we always compare white guys to other white guys? There is no reason Redick can't be another Rip Hamilton in the NBA. Hamilton was never very gifted defensively, but worked his *** off to become a solid defensive player. Redick appears to be working toward that same goal. The conditioning and the quick stop-and-pop release, and the uncanny accuracy from mid-range are also similar.
