Muggsy Bogues averaged 2.6 rebound per game in 28.6 minutes per game. A few more inches would have helped in the rebounding department.
I've watch Dennis Rodman play live. I've seen lots of games live, lots of players. Rodman wanted the rebound more than anyone on the court. Timing, depth perception, instinct, innate internal physics/trigonometric calculator (got one?), eye sight, coordination, strength, height, quickness, leaping ability... all these are parts of rebounding. Rodman wanted the ball more than anyone else. Call it aggressiveness, desire, pride, whatever. Just like Michael Jordan would get the look like he wanted to score and somehow always did when he wanted it, Rodman went after every rebound. He was never the biggest or fastest or quickest guy on the court. He was the hungriest.
Of course, then he'd sometimes go to sleep on the offensive side of things. But he'd wake up when somebody shot the ball (4.8 offensive rebounds per game in 31.7 mpg).
Don't ask what sort of Chunks they are, you probably don't want to know. Blowing Chunks since Season 4!
