Almost every statistical analysis of Lee's fielding says he's average at worst, while watching him it is hard to believe. I think the reason is that with his huge legs and long strides, he is running a lot faster than we think. As far as his blunders (like calling for a ball that landed 10 rows into the stands), range is much more important that fielding percentage, e.g. Jose Valentin, and he will be an offensive powerhouse this year - as was last year after June 1st, when he figured out the strike zone.
