This is for all the "it's not variance! It's lazy defense!" people.
It's basically the definition of variance, and Miami has gone on insane heaters against Boston that literally no one else does, against all types of defenses.
However, it is true that the Heat were generating more decent 3s this game, even if you'd expect them to shoot more like 36-40% on those. The Celtics made an adjustment late that worked, and that we'll probably see more of: they put Tatum/Brown/Jrue on Bam, so that they could switch every PnR. They also pre-switched KP out of actions whenever Miami wanted that. Miami still got 3s, but they were crappier, contested, and above the break. Of course they went in, but it happens.
We'll probably see more of KP off Bam, since Bam was making every garbage mid-ranger against KP and Al anyway, so may as well put wings on him.
