1. Tim Duncan: Because he does everything. Score, rebound, pass and defend. And because an outstanding big can directly and indirectly influence any given ball game much more so than a little or a medium.
2. Kobe Bryant: Because he also can do everything (when the spirit and/or Phil Jackson moves him). Kobe is certainly the best non-big in the game, a superb rebounder, an unparalleled clutch scorer, a terrific prac ioner of both perimeter shot-making and irresistible penetrations, a potential shut-down defender (see the above qualification) and an adept (if not always an eager) passer. It's his versatility that separates him from the other non-centers.
3. Dwyane Wade: Because of his dynamic talents, his clutch performances and because he works hard to improve his weaknesses (defense and outside shooting).
4. LeBron James: Because of his rare combination of skills, speed and strength. LBJ is not rated any higher because his defense is still atrocious, and because his long-distance dialing remains iffy.
5. Steve Nash: Because of the (nearly) unblemished fashion in which he orchestrates the Suns' offense. Indeed, it's Nash's vision, unselfishness and ability to create his own shot opportunities that have unilaterally made a terrific team out of what is only a good team. His only flaws are a total lack of straight-up defense and a fragile physique.
6. Shawn Marion: Because he can score without having his number called, he can rebound like a big and he can play top-notch defense (albeit not as consistently as he used to).
7. Chauncey Billups: Because he's a master of all trades. In the clutch, Billups can come up with whatever play is needed to produce a win — from a score to a rebound to a stop to a perfect pass.
