Yeah, I don't consiider him a can't miss type player. Because when iit comes to H.S. hitters they can be fairly risky, and only the Griffy's/A-Rod's deserve the can't miss label.
Butler is right there with Nelson though, for the best bat to come out of the 2004 draft. With the polish he has shown already for such a young hitter, it seems he won't have any plate disicipline issues. I'd say he very well could be a top prospect after this year, he has played better then I thought he would.
