My main problem was his offensive rebounding point. He says that nobody talks about how little the offensive rebounding and second chance points the Celtics get because they have the highest FG%.
He needs to know that those things are CORRELATED.
If you make the most shots, you obviously have less chances to GET an offensive rebound. Also, against many teams, NOT going for offensive rebounds make you better defensively. Popovich's advice to the Spurs when going against the Suns and the Nets in the playoffs was specifically to not attempt any offensive rebounds and run back on D.
But to prove my point on the offensive rebounding stat?
09-10 (to date): Celtics 1st in FG%, 29th in ORB
08-09: Suns 1st in FG%, 16th in ORB
07-08: Suns 1st in FG%, 30th in ORB
06-07: Suns 1st in FG%, 30th in ORB
05-06: Suns 1st in FG%, 30th in ORB
Now it may not be a correlation since these are just 2 teams, but it is mathematically obvious that better offensive teams have less ORB. In fact, there's a reason why teams have HIGHER ORB's than the Celtics; because they miss more shots.
When the Celtics give up more ORBs, I'm never worried if we made more shots. Because that makes sense. It's when give up offensive rebounds and shoot more poorly than our competition, that's when I worry.
