For several seasons, no NBA team has used the zone defense as much as Miami. Erik Spoelstra has clearly made it an important weapon in his arsenal. This season alone, with 575 defensive possessions in the zone, it’s the highest number in the league in 2025/26. However, this is not the only solution for the coach, who remains critical of this option.
“There are times when I hate it,” he clearly states. “Because sometimes there isn’t a definitive responsibility. Sometimes we think the zone will allow us to get by and that we don’t need to work as hard. Nothing could be further from the truth.”
According to Spoelstra, zone defense is not for resting or should not be approached as a way to hide. To be effective, it requires intelligence and effort.
“In reality, we probably burn more calories in zone defense than in individual defense. There are a lot of different movements to make,” he continues. “It’s part of our defensive system, but it’s not the only system. We are never better than in individual defense.”
Forcing opposing attacks to (over)think
When done well, the zone disrupts attacks on a large scale. Kevin Durant and the Rockets experienced this during their visit to Miami, facing the 46 possessions (his season record) where the Heat used this defense.
“No matter our defensive scheme, the goal is to make things difficult. Here, we were in the zone, we controlled the spaces and fought to contest shots near the basket,” the coach analyzes. “In defeats in the last three months, we gave up shots near the basket and 3-pointers. Here, in zone or man-to-man, we contested 83% of 3-point shots in this victory.”
With 111.5 points conceded per 100 possessions, the Floridians have the fourth-best defense in the NBA behind Oklahoma City, Detroit, and San Antonio. Whether he loves it a little, a lot, madly, or not at all, Erik Spoelstra knows he’s on the right track with the zone defense. The players do too.
“It’s an excellent adjustment because we can pull it out of our hat and be effective with it,” Davion Mitchell says. “Especially against big scorers like Kevin Durant, who can change a game with their points. Putting a zone in front of them forces them to think a little.”
