"The best rebounders aren't tall guys. A lot of good and great rebounders have been under 7'0. Buck Williams, Charles Oakley, Elvin Hayes, Bill Russell, Jerry Lucas, Charles Barkley."
Um, no. The best rebounders are tall guys. Wilt Chamberlin, Kareem, Dwight Howard, Marcus Camby. And Bill Russell, Buck Williams and Elvin Hayes are also considered tall by the way.
The only reason that Muresan and Bol played in the NBA (and perhaps basketball at all) was because of the general advantage height has in the game of basketball. Anybody shorter than them with the same skill set would never have made the NBA in the first place. The shorter you are, the more amazing your skill set has to be just to compete with players who can practically touch the rim without jumping.
