And for as awesome as Andruw was defensively, he never really hit his full potential offensively. Now whether having that extra time in the minors would have made him a better hitter is questionable, but leapfrogging through levels definitely didn't help him. You have to give the players a chance to struggle so they can learn to make adjustments. When you move them so fast they don't even see pitchers more than once then nobody makes adjustments to them, and in turn they don't get a chance to learn to adjust.
And clearly they are planning on starting them at the beginning of next year, but it's pretty dumb. And it's being done for financial reasons (to drum up interest in the club for the new park), not developmental reasons.
