I don’t buy that Bamba’s issue is that he’s lazy— that shows up on some plays, sure, but that’s only 5% of the problem with Mo, if that. If he was playing defense at the level he’s capable of, we’d brush over him not running back for a chase down block since he’d be more than capable of it. His motor is more of an annoyance rather than a legitimate reason he’s not playing well.
When I watch Bamba, he looks lost on the defensive end. He’s tentative and often looks unsure about his assignment and defensive positioning. He’s late on rotations and on help defense, which is where Bamba derives so much of his value. When defending players outside the paint, he’s hesitant to use his length to defend jumpers out of fear of fouling. His inconsistency comes from a lack of mental understanding— when you watch Vuc, regardless of his athletic limitations, he’s always automatic in regards to knowing his assignments, pick and roll coverages and when and how to rotate. There’s no peeking back over his shoulder to see if he’s wrong in the way that Bamba always does. If Bamba played with his balls to the wall like you want him to, he’d foul out in 8 minutes and give up several easy buckets because his understanding of the defense just isn’t there.
When Bamba stops thinking and just starts to react, he’ll be fine. I’m not sure if he’ll get to the point like Vuc or Birch where playing defense is like muscle memory, but it’s fairly obvious to me that Bamba’s extremely tentative on the court with making decisions, and it’s extremely detrimental. On defense, you don’t really have time to think— it’s react and make a play, and Bamba can’t really do that right now, certainly not in the same way that Birch or Vuc can. If he could, we wouldn’t be talking about his effort.
I think benching Bamba would be the worst thing. Give him every rep possible and hope he turns a corner mentally, or trade him and play Birch or a center you acquire. Benching him would make him even more tentative, and that’s something you don’t want.
