@RchfldCavRaised you know how much I appreciate your opinions. And this isn't a post to defend JBB, god knows I've been getting more progressively frustrated with his decision making (or lack thereof) in the last few months of the season. That said...
I think everyone's in a position where JBB is getting blamed for damned if you do, damned if you don't decisions he's forced to make because of the roster's limitations. Playing Moses Brown is a perfect example of this. I think not playing Brown was probably the right decision, and if you disagree I'll point you towards the Dallas and Atlanta games near the end of the season. It was an absolute nightmare highlight reel of Trae and Luka just putting him in the high pick and roll. Brown either refused to leave the paint leaving open pick and pop shots for his man, or was absolutely lost trying to defend the driver in space/in drop coverage. If you put Mobley on KD, KD will get a pick (Mobley will probably never be good in fighting over picks a la Giannis, it's just hard to be good with their dimensions) and then all of a sudden you have Moses defending against KD in space (because you can't just let KD walk into open jumpers), maybe the greatest scorer in NBA history.
Added to which, Mobley was the ONLY guy on our team who was providing paint protection against Brooklyn. Assuming Brown is unplayable for the reasons I outlined above, you need to play Love and theoretically Lauri because they're the only other bigs and offer spacing/scoring, but then they're also complete pushovers defending the rim. If he wasn't at the rim, Brooklyn was just about guaranteed a score- when Mobley was there to contest, he blocked 2 shots and had awesome verticality plays on a couple of layups and contested a few more for misses. If you put him on KD, all of a sudden he's spaced out 25 feet from the basket on most possessions and now you're counting on Love or Lauri to lock down the paint.
If JA was back, obviously this changes everything because Mobley could be on KD or roaming off of Bruce Brown and we wouldn't be losing the rim protection. But with him out, it's a clear damned if you do (Brown defending pnr and in space) or damned if you don't (Lauri and Love can't protect the rim, Lauri also can't rebound) and neither option is any good.
Normally I'm not a fan of trapping the ball handler like we did in the 2nd half, but it's Kyrie and KD hitting every single contested shot and in a single game elimination you've got to try something. I thought the plan worked about as well as it could as long as they weren't making Mobley's man set the pick- he did a great job contesting Brown on the 4 on 3s while not giving up an easy lob. There were some tough floaters/layups as well as undoubtedly preventing KD and Kyrie from shooting more than they did. Once they got Mobley in the action, then you really saw the limitations of Love/Lauri down low. If that was JA, he's probably even better than Mobley at staying attached to his man while contesting the shot.
I feel like a lot of these decisions we're having are versions of Lakers fans getting mad at Vogel for playing Avery Bradley over Reaves, THT, etc too much. If you have to have the discussion, oftentimes it's because neither option is particularly good. I've got a
whole lot more on my frustrations of how we're building the roster, but that will have to wait till the season is over.
