J.D. Drew - Defense

Obviously I haven't seen him play a lot, so I can't comment from personal observation.
Here's how Drew compares to other MLB rightfielders in the various statistical metrics:

Fielding Percentage (putouts + assists / chances): .983 (6^th)
Range Factor (putouts + assists / innings played at the position): 2.91 (3^rd)
Zone Rating (balls fielded/total balls hit into his “zone”): .891 (5^th)
Probabilistic Model of Range (difference between actual outs and predicted outs): 10^th

^{Oh, and he's a solid baserunner.}
