The point about Mike Malone is not that he played Jokic or didn't play Jokic. The point is that he is the same coach who was revered after winning a championship, with so many, "if we only had Malone and not Mazzulla", and so on. Now DEN has a collapse, blowing a lead in a game 7 at home, after getting blown out in a potential close out game 6, and he doesn't look any better than Mazzulla.
This could mean that both Mazzulla and Malone are bad coaches, it could mean they are both good coaches (title caliber coaches), or it may not mean that much at all about either coach. The lesson I believe is that you shouldn't be so quick to deem a coach a bad coach or a good coach.
