The rebounding on the other hand I don't have much hope for. Bass can only do so much, especially with Olynyk giving up a huge disadvantage. Humphries hasn't been anywhere close to his previous level, while Green, Bradley, Crawford, and Brooks are nonexistent on the boards. That's right, 5/10 of our regular rotation completely sucks at rebounding and Wallace/Lee/Humphries/Bass are only average. We're somehow only counting on one good rebounder in Sully and he's averaging what? 6 per game?
You think Bass is an average rebounder? If only. He's in the same bad and/or nonexistent category as Green and the guards are. I don't know how you could've watched Bass the last two seasons and categorized him as an average rebounder. His total rebounding rate is very good for a small forward, which means it's abysmal for a power forward.
Humphries, on the other hand, is a well-above average rebounder but may not be one if he has to go up against much bigger centers most of the time.
Wallace is a very good rebounder for a small forward. He's actually one of the best.
Whether the guards are good rebounders or not, that doesn't move the needle much overall. The Celtics would be a good rebounding team if they played a frontcourt of Sullinger, Humphries and Wallace. Since Bass, Green and Olynyk are likely to get ample playing time, rebounding should remain a problem this season. From Rasheed to Jermaine to Big Baby and Bass, the Celtics have had bad links in the chain in the rebounding department that have killed them.
