You're wrong.  Rebounding is done on a team basis, with rebounds later allocated to individual players.  However, there are positional modifiers weighting the importance of each position to the team rebounding.  In other words, when a rebound is determined, it compares each team's aggregate rebounding score.  But that aggregate score isn't just the sum of the rebounding ratings of the players on the floor.  It isn't even just the sum of the players' overall rebounding abilities (primarily some combination of REB and ATH, weighted heavily towards REB).  It's something like 1*CTREB + 1*PFTREB + .5*SFTREB + .2PGTREB + .2SGTREB, where TREB is some total rebounding metric.  Those numbers aren't precise, and I have decent numbers, but I won't give them away in extreme detail.  As simple estimates those aren't horrible.

Except, dahs, don't I remember something about a change that makes positional mismatches more important? 

Here it is.

2-16-2011 update notes ...

Added an individual player matchup component to rebounding, so that a mismatch will produce better numbers from the player with the advantage. This will in turn create a little more separation between the truly good rebounding teams and poor rebounding teams.

So I'm not sure I understand 100% what your saying.  But it sounds like you agree withe me.  Cuz basically what your saying is, that the better rebounding ratings your guards have the more likely your center is to get a rebound.

Not exactly, but almost.  In his example/equation:  A guard with 100 rebounding rating is worth 20 rebounding rating on Center (because it's weighted differently due to position).  Yes the guard rating does impact the overall team rebounding rating, but not as much as you may think because of his position in the starting line up (his actual position given by WIS doesn't matter really, especially since there is not position penatly). 

So if you take a guard with 50 rebounding and factor in the position he is playing on the court - it's really just worth 10.... which is not likely to make that much of a difference over the course of a whole season.

Keep in mind, he's not saying the those are the exact modifiers.... that's top secret.

Now, if you played the guard in the center position... I assume his effectiveness would improve because the modifier would not apply??

why would someone have good information and not be willing to share it?  I have never understood people who want to win on an unfair playing field but I guess different people is what makes the world go 'round.
