Is this even a discussion? Why has Walker more potential? I mean, he can end up being the better player, but why would anyone consider him the better prospect now?
The way I see it, it's Hickson by a fair margin. I've always sensed Walker is a tad over-rated by fans (and not especially Celtics ones). I think it's because of his association to players like Mayo and Beasley (and the exposure that granted him), the fact he was highly ranked coming out of high-school and the fact he's a scorer and a high-flyer dunker. But nothing of that matters when evaluating his NBA potential... Walker, coming out of college, wasn't/isn't:
- a good ball-handler
- a good shooter
- a good defender
that conjugation of (lack of) skills is fatal for a NBA wing player. Guys can get away with 2 of those traits, but the 3 of them? Almost impossible, they must be very polished and wise. He can improve, but his potential is limited by the chances of him not improving that much on any of them. That's why I was surprised by so many people believing he'd be ready to contribute this season right away (and why I thought it'd be wise to send him to Europe).
Hickson is already a good player, albeit very raw on some aspects of the game, one year younger than Walker and I can see him being a solid starting big man for good NBA teams. If Hickson was anywhere near his peak, I could understand the view that Walker is the better prospect if JJ Hickson was some college senior near his peak, but Hickson is also a "potential pick" and his athletic abilities are at least as impressive as Walker's. Plus, he's the big man.
I think it's very difficult to make a rational and convincing defence of Walker as the better prospect. Hopefully he'll be the better player down the road, but stating that now is more a leap of faith than anything else.
