Shabazz Muhammad's season ended on Friday at the hands of Minnesota. The Bruins had two big things working against them: the injury to Jordan Adams and the task of keeping Minnesota off the boards. The Golden Gophers are first in the country in offensive rebound percentage, grabbing 44% of their missed shots. On the other hand, UCLA has struggled all season long with rebounding. They rank 206th in the country in offensive rebounding and 264th in the country in defensive rebounding. At 6'6", Shabazz's personal OReb% was a solid 9.9%, but his DReb% was an awful 8.5%. To put that into perspective, Gonzaga's 5'11" David Stockton's was higher this season (9.2%).
Trying to keep Minnesota off the offensive glass had to have been a main priority for Ben Howland on Friday. The Bruins as a whole actually did a pretty good job of this. Minnesota had 10 offensive rebounds (32.4% OReb%, well below their season average). Still, if you look at the box score you will see that Shabazz had ZERO defensive rebounds in 39 minutes. That's actually pretty hard to do, you would think a ball is going to fall in your lap at some point in the game.
How does an athletic 6'6" forward not get a single defensive rebound in 39 minutes? Well to answer that question I decided to go back and look at the film. Of Minnesota's 10 offensive rebounds, Shabazz was on the court for nine of them. The photos below highlight where Shabazz was on the court when Minnesota got their nine rebounds.
1. In good position but flat footed, spectating
For Shabazz's sake, I was hoping the reason for his lack of rebounding was to leak out in transition. Although this might not be an optimal strategy, it would mean there is at least an advantage to his lack of rebounding. Otherwise, Shabazz is simply very bad at the skills involved in rebounding or not hustling (or both). This first attempt shows a flat footed Shabazz under the hoop. In his defense, he has three UCLA teammates in the paint with him.
2. Boxing out
The problem with this analysis is we can't be sure of Howland's gameplan. Basketball purists are quick to teach the box out, but the fact is that's much easier said than done against Minnesota. Still, I think it's safe to say that Shabazz did a pretty good job on this possession
3. Late getting back in transition
Here Minnesota got an easy put back in transition off of Shabazz's miss on the other end. He was very late getting back, but we're not too concerned about this one in terms of rebounding ability.
4. Sort of boxing out the shooter
Shabazz was guarding the initial shooter on this one. He didn't box out immediately, but at least tried to recover after he realized the ball wasn't going in.
5. Flat footed, spectating
The ball doesn't go to Shabazz's side, but he is still pretty much just standing and watching the play unfold. This is an example of the worst scenario for Shabazz. There are obviously very few times in a basketball game where standing and watching isn't a bad thing.
6. Elevating for the rebound
Shabazz gets his hand on this ball, but was not able to come up with it. The ball got batted out for a long rebound. By getting his hand on the ball, he may have prevented an easy layup for Minnesota (even though they were still able to maintain possession).
7. Flat footed, spectating
Another negative play for Shabazz. He's not boxing out or going after the ball. He's not even leaking out, he's just standing and watching.
8. In good position but flat footed, spectating
More of the same here.
9. A bit more of pursuit
Shabazz took steps towards the basket to potentially grab a rebound, but the ball bounced off the rim hard. You can see in the photo he is changing his momentum to either try to continue to pursue the ball or possibly to leak out.
Obviously, this analysis is only nine plays from one game and is by no means definitive. I'll let the film speak for itself and not over generalize, but Shabazz's rebounding (and motor) might be a long term concern for his NBA career. Statistically, his rebounding numbers are somewhat similar to DeMar DeRozan. DeRozan was a pretty good offensive rebounder and a not so good defensive rebounder, but not quite as bad as Shabazz.
