Spoelstra is looking to jump-start a sluggish offense by inserting the hot-shooting Miller into the starting lineup of Thursday night's Game 4.
Replacing Haslem with Miller would give the Heat more shooters in an attempt to spread the floor. The Spurs have been successful in packing the paint over the series first three games and it has cramped the driving space for LeBron James and Dwyane Wade .
At shootaround Thursday before Game 4, Spoelstra said he doesn't expect a dramatic increase in Miller's minutes. When asked if the Heat would play Miller more, Spoelstra indicated the quality of minutes was more important.
"We'll see," Spoelstra said. "He's already been a big part of this series. He's playing good minutes. Whether that's more, we'll see.
"He's giving us everything he's got. At this point, those efficient, impactful bursts are the key."
No coach ever wants to make the first move to adjust the starting lineup, and Haslem has been key in containing Tim Duncan. A move like that would necessitate James playing defensively as a 4 or 5 more, something he's been hesitant to do in the past. It would certainly seem that down 2-1 on the road with two more games to go against the Spurs in San Antonio, the Heat are starting to get a bit desperate, particularly after the demoralizing loss in Game 3.
