I am not sure if there are other reasons but I can say with 100% confidence that carrying 80 pounds of extra fat will lower your ability as a baseball player. 80 extra pounds? If Prince's ability wasn't hindered in 2007, the argument here would have to be that he gained 80 pounds. It's baseball -- it's variance. Well, coupled with unrealistic expectations from the fans. Guys just don't hit 50 bombs every season. I'm certainly not disappointed with Prince's season. His plate discipline has gotten even better, and like Ennder said, with that one huge hot stretch that still may be coming, this discussion really isn't even sensible. Now of course he hasn't gotten hot like that yet (insane hot streak), but just pointing out how small the difference is. As of today, his BA is actually lower at this point than 2006, but his OBP is 20 points higher, and his OPS+ is 12 points higher. I think that, in general, he's showing growth & polish as a hitter, and that's about all I can ask for in a 24-year old. I really think that Prince is either going to have a monstrous power surge in September, or continued improvement in his OBP. I'd be fine with either one.
