The key here is to limit 3-point looks for the Heat’s good shooters and give open shots to their shaky shooters. To this end, set the defense on Mario Chalmers, Ray Allen, Mike Miller and Shane Battier to tight both on-ball and off-ball (Miller likely won’t see the court, but you know, just in case). You’ll also want to set the defense for Udonis Haslem to sag off when he doesn’t have the ball. Ideally this will goad the Heat into passing to him and him taking shots. He’s a decent mid-range shooter, but you’d rather have him shooting than just about any of the other Heat players save Joel Anthony, who doesn’t see much court time.
What both the previous step and this step are trying to do together is not create an iron wall of defense—because that’s hopeless against Miami—but to create a funnel of ball movement that makes the Heat take bad shots. If a defensive possession ends with Bosh or Haslem taking a midrange jumper, James or Wade driving into double coverage, or any player throwing the ball out of bounds because they’re being double-covered, it’s a success.
