Forget scoring, where's Millsap's rebounding gone?
Edit: And to pre-emptively answer the question of "since when was 8.5 RPG bad?": Since playing 36 MPG and it was the primary reason he is even in the league. He's 58th in rebounds per 48 minutes at 11.1, and 33rd in rebound rate (I'm honestly not sure what the difference is, but neither show that he's anything more than an average rebounder).
