It's just funny that it was JR Smith which was focused here.
Probably because he has gotten many times of suspension in anti-drugs. 
I do remember though one part in Last Dance when Michael found something when he entered the room of his teammates back when he was still young. Looks like this is normal for them when no test for recreational drugs will happen.
Let us not jump to conclusions about the Spurs.
Difficult: Hardcore
But, a chance is still there for them.
If other teams lose their game and Spurs is still at their best then a snatch for the 8th seed could come true.
