Times have changed. If a player in today's NBA records 20 or more rebounds a single game, it is thought be an excellent game. But to average over 22 rebounds per game over your entire career is pretty amazing, a feat only accomplished by the Legends, Wilt Chamberlain and Bill Russell.

Dwight Howard is the highest ranked active player, recording 12.2 RPG over his 4 year career. There are a total of 5 active players on this NBA records list; Howard, Shaquille O'Neal, Tim Duncan, Kevin Garnett, and Emeka Okafor.
