Good rebounders are born, not created. Francis averaged 5.4 rebounds per 36 minutes for his career. He started at 5.3 in his rookie season and never got much better or worse. Bayless has averaged 3.1 rebounds per 36 minutes both seasons. He's about as good as he'll ever be at rebounding. It's very, very rare that a guy figures out how to rebound. People have been waiting for Aldridge to learn how to be a man and rebound, but it's never going to happen. Check it out... rookie season reb/36 minutes/career average Gerald Wallace 7.5/7.2 Lamarcus Aldridge 8.1/7.7 Brandon Roy 4.5/4.5 Jason Kidd 5.4/6.7 Travis Outlaw 5.5/5.6 Chris Paul 5.1/4.7 Magic Johnson 7.7/7.1 etc, etc, etc Kidd is the biggest improvement I found of the guys that came to mind and he only increased his rebounding by 1.3 per 36 minutes. Bayless won't suddenly become a good rebounder.
