Time to stop underselling his postseason coaching. He has decent foresight. Every series we've played we know what type of shot we are willing to concede to what player on the other team, who and when to trap, whose screen to go under. Our average defense is able to regulate our opponent's offense thanks to this. His timeout plays are money. He doesn't stick with a predetermined setup when it's clear it isn't working. He doesn't use the wait and see aprroach other coaches use.
Whereas he's constantly put down in favour of 'superior' coaches like Eric Spoelstra who for instance in the 2014 finals didnt have the basic tactical nous to tweak his system not to trap a guy like Boris diaw when it became obvious he was only looking to make the extra pass out of the double team.
