I thought we were talking about rebounding. I was only responding to your nonsensical response (that 7th of 8 is above average).
The stats point to Jefferson being at best an average rebounder at the 5. Nothing I saw throughout the season leads me to believe otherwise. Do you really think he's an above average rebounder at his position?
The 8 centers who play over 30 mpg are all really good. That is why they play over 30 mpg. Each one of those centers is either an All-Star, or an All-Defensive team type player (Save Monroe and Gortat).
Dwight Howard (All-Star) - Has no challenge for rebounds on his team. He is pretty much the responsible for all of their rebounding. Also clearly way better than anyone in the NBA at rebounding regardless.
Marc Gasol (All Star) - Actually one of the ones with a RPG less than Al's, despite playing more minutes and having Zach Randolph injured for a large part of the season.
Andrew Bynum (All Star) - 7' athletic center.
Tyson Chandler (Defensive Player of the Year) - His sole role on the team is to rebound and play defense. He fights Amare for rebounds. All of that, and he is still barely rebounds better than Al.
Marcin Gortat - One of the 8 who isn't an All-Star. He does play on a fast paced Suns team that has 0 true power forwards to challenge him for rebounds. The Suns were also one of the worst rebounding teams in the league.
Greg Monroe - Another one of the non-stars. Same thing with Monroe happens that happens with Gorat. He plays next to ZERO rebounders. He is the only person capable on the team of grabbing over 8 rebounds any given night.
Joakihm Noah (All Defensive 2nd team) - Great rebounder, but is another player who is solely focused on defense/rebounding. Clearly a better rebounder than Jefferson regardless, but he doesn't have half of Jefferson's offensive responsibilities.
And finally
Al Jefferson. Other than Howard (Gasol may be equal), probably has the most offensive responsibilities than anyone on the list. He also plays with 3 other good rebounders. Millsap has always been a good rebounder and he also play alongside Derrick Favors for stretches, who is a dominant rebounder.
Not saying Jefferson is the best rebounder of this bunch, but I would probably put him around the middle of this group. Even if he was the worst on this group, everyone in this list is above-average rebounder.
