This ranking is purely statistical and very shallow. It's based on 2006 stats so (for instance) Danks is still included in the Rangers ranking. The only stats used are OPS for batters and OPS-against for pitchers, and they only considered players at Low-A or higher. To rank systems, he attempts to quantify "studs" and "depth" by seeing where each player performed compared to other players in his age group.

One thing that stands out to me is that the Devil Rays are ranked 14th -- does this show some of the disconnect between performance and athleticism, or is this primarily because the D-Rays have a lot of high school picks?
