I'm sure they want to win but on their own terms. Bron has never been this inefficient in his career and I don't think some major decline is happening. He's just purposely taking bad shots. AD is purposely shutting it down once he reaches his averages. A team that is this good defensively is usually hovering around .500. Guys just don't care about winning.
If that was true, that would be way worse than the other option.
Bron is taking bad shots because he can't get around defenders like he used to be able to do. He's been settling for bad shos for a WHILE now. A lot of the issues that are becoming super obvious have BEEN going on (getting hunted on defense, bad shots, pnr not being respected) it's just becoming undeniable now and people still can't wrap their heads around it so they jump to conclusions like these.
