Butler was in season-long load management and is gradually entering beast mode as per schedule.
Last game, Spoelstra almost brought the Heat back by having him check Brunson in the 2cnd half, but switching onto Julius on handoffs or picks thereby singlehandedly nullifying both our stars on every possession.
This game, he went with straighter Butler on JB and Bam on Randle when it mattered.
When Butler levels up, they are one tough team, for us, and for whoever they face in the playoffs.
