I think at some point the next wave of AAA guys will come up for a look see. But you are equating minor league numbers with major league performance.
Isn't it an exaggeration to say that Dickerson is better than Junior, Hopper, Freel, Patterson and Hairston? Based on an .816 minor league OPS in his good period? (Overall Dickerson's minor league OPS is .767.)
Yes, I'm in favor of giving Dickerson a shot. I thought he might even be a fourth or fifth outfielder all season.
But let's keep some perspective about him and the other minor league guys. They may be able to contribute some day, but very, very few are destined to be good players on a winning team.
