I re-studied (not sure that's a word) some fielding stats on the ESPN site last night, and noticed that when it came to CF fielding percentage, they were extremely close...with PB just barely higher than Trout, but in range factor they were further apart.
Trout's RF was 2.70, and Bourjos's was 2.98. Experts say PB has more range and speed in CF than Trout.
I'd just as soon watch the two of them out there together no matter which OF position they each play. It's fun.
