The player Delmon reminded me most of, from the time he was drafted to now, is Andre Dawson. From the huge arm in RF to the aggressiveness at the plate and the ability to steal bases... that's who he reminds me of. And he has the potential to be better than the Hawk. Yeah, he doesn't walk a lot, but he does have a good eye. I know it's hard to believe, but based on watching him with Tampa this past season... he's very aggressive on the first pitch, and falls behind 0-2 a lot, but he doesn't swing at a lot of bad pitches (ala, Jeff Francouer). When he sees a pitch he think he can't hit, he usually lays off of it. He's very aggressive within the strike zone, but not so much outside of it.
I think, as time goes on and with the respect he'll garner for his hitting prowess, and as he figures pitchers out more, he'll start to take more walks. There were several managers calling him a Hall of Famer after 126 ABs in the majors, and even a couple hinted the name Frank Robinson after seeing him play. Don't believe me? There's a blog from Peter Gammons for insiders on ESPN.com that mentions that very thing. I'm not ready to bust out the comparisons to an all-time great like Frank Robinson, but that's how a lot of people see his ceiling as (He's also been compared to Albert Belle, who, if not for all his problems, would of been a HoF lock).
Delmon Young will be a great major league player... I'd be shocked if he wasn't.
