I have some serious concerns about the Celtics ability to rebound the ball with the current roster as constructed.
Last season, the Celtics were below average, or 18th in the league in total rebounding % at 49.4%, and among the worst defensive rebounding % teams at 25th.
We lost Sullinger, who was by far our best rebounder on the team, with a defensive reb% of 27.1% and total reb % of 18.7%. Excluding David Lee, Amir and Jerebko were our two next best rebounders, at roughly 19.5% defensive reb % and 14.9% and 13.3% total reb%, respectively.
With the loss of Sullinger, the Celtics project to be even worse than last season. Horford's RPG has declined over past seasons, possibly in some part due to his increased role on the perimeter. His defensive reb% was 18% and his total reb% was 12.2% with the Hawks last season, with a RPG of 7.3 over 32.1 minutes. Definitely not on Sully's level as a rebounder, even though he is a far superior player. Notably, Horford did average roughly 9-10 rebounds per game earlier in his career, but this was with more minutes per game.
We have too many weak rebounders on our team, especially our bigs. Olynyk and Zeller are weak. Mickey is suspect. Rozier is a strong rebounding guard, but we can't hinge our rebounding needs on a ballhandler (as termed in Stevens' system, or PG/SG, whatever you want to call it), much less a ballhandler who will likely be receiving limited minutes barring injury to our starting guards.
Our starting lineup, which will probably be Amir, Horford, Crowder, AB, and IT, I think will be able to do a passable job rebounding the ball; however, once we mix and match our star or play small lineups is when we're going to have problems.
We're going to be a great defensive team - again. But nothing is more frustrating than playing 18-23 seconds of great defense and forcing a missed shot, only to surrender an offensive rebound.
Thoughts? Are these concerns overstated? Will Crowder, Brown, Smart, etc. be able to contribute enough to keep us competitive on the rebounding front?
