I tend to agree that he is probably not a major league starter, but not cause he can't field first base. That anonymous qoute about learning the position is off base, IMO.
I give the guy credit: he's been moved around, hasn't publically whined, seems like has progressed beyond what many predicted (just a token pick to please his dad), has surpassed most of the crappy picks from that time period, and he hustled in the games I saw. He just misses too many pitches.
