I'd be pretty happy (if not super-hyped) about either those three guys.
I see Gordon as a future Dennis Rodman - super athletic swingman with great motor and the potential to be an All-Defensive first teamer in the future.
I see Vonleh as a future Amare Stoudemire - fairly athletic big man who can score inside and out, is a strong 1-on-1 defender and rim protector, and a very good rebounder. I don't really see the Bosh coparison because Vonleh doesn't seem to have Bosh's "don't touch me!!" softness and looks to be a much better rebounder and shotblocker. Still, I'd be pretty happy as either an Amare or a Bosh.
I see Smart as a future Dwayne Wade. His jumpshot needs improving but he's a pretty athletic (if not super athletic) player who is tough as nails, is a natural born leader, can play either guard position, plays both ends of the court, and isn't afraid to take the big shot.
When the your consolation prize is a Dennis Rodman, Amare Stoudemire, Chris Bosh or Dwyane Wade...I'm pretty cool with that.
