All we know is what we see on the floor, which has been confusing. We see incredible body movement from Heat players and creativity that few other coaches match. Just in the last game, the decision to run low Chalmers-James pick and rolls was a sign of very good coaching.
But we also see the so-called "on and off switch" that causes the Heat to come out flat at times. This, and a few other issues, are indicative of not-so-good coaching.
Not every coach is Gregg Popovich, but the juxtaposition of this series underlines Spoelstra's weaknesses. I don't think he has control over the emotions of this team and I don't even blame him for it. Pat Riley put together a team of three superstars all at once and there are only a hand full of coaches in history that would be able to meld such a collection and into a truly cohesive unit.
But by now, three years in, the fact that you can tell when the Heat are on just by looking at the intensity level of a few key players is worrisome. LeBron is the best player in the world and I am an unapologetic fan of his, but it is unacceptable for your star player to fluctuate emotionally so much. I am not saying he needs to score more or pass more. He needs to focus more. And that's part of Spoelstra's job.
And Dwyane Wade, who Spoelstra has been coaching for an additional two seasons, is the team's true wild card. His varying production is a weakness for the team--a weakness that the coach must surely recognize. Wade has even stated publicly that he doesn't know what he can give quarter to quarter.
In retrospect, Spoelstra should have been managing Wade's minutes more carefully for the last season or two, like Pop does, and now it seems to be too late to jerk his playing time around. When a star is ailing and can only be productive in bursts, the coach needs to use that to his advantage and control those bursts, not passively fall victim to them.
