Zone has been a big part of the Miami Heat’s defensive system for years. In fact, the Heat has led the NBA in zone possessions played in three straight seasons.
But even with the Heat on track to again lead the league in zone possessions for a fourth straight season, coach Erik Spoelstra doesn’t always love turning to the scheme.
“There are times when I hate it,” Heat coach Erik Spoelstra admitted following Monday’s practice at Kaseya Center. “Because there’s not definitive accountability sometimes. And sometimes you have a mind-set that the zone is going to bail you out, or you don’t have to work as hard. That couldn’t be further from the truth.
“We actually have to arguably burn more calories in the zone than we do in the man. And there are a lot of different movements that happen. But it’s a part of our defensive system. It’s not the only part of it. Obviously, our fastball is our man-to-man defense when we’re at our best.”
The Heat, which entered Monday with a league-high 575 zone possessions used this season, turned to its zone defense a lot during Saturday’s home win over the Houston Rockets.
According to Genius Sports, the Heat used zone defense on a season-high 46 possessions on Saturday and it worked. The Rockets scored just 0.65 points per possession against the Heat’s zone.
“Regardless of whatever the scheme is, I always go back to that, it’s just about committing to doing hard things,” Spoelstra continued, with the Heat set to continue its homestand on Tuesday against the Brooklyn Nets at Kaseya Center (7:30 p.m., FanDuel Sports Network Sun). “I mean, we were really moving in the zone, and taking away airspace, and scrambling to challenge shots at the rim [on Saturday]. In a lot of these losses in the last three months, we’ve just been giving up shots at the rim and threes. And we had an 83% contest rate on threes during the course of the game, and that was man or zone.”
Whether in zone or man, the Heat has featured one of the NBA’s top defenses this season. Miami entered Monday with the league’s fourth-best defensive rating, allowing 111.5 points per 100 possessions this season.
“It’s a good adjustment, especially because we can pull that out of our pocket and be real effective with it,” Heat starting guard Davion Mitchell said of the zone look. “Especially with guys who can score the ball, guys like [Rockets forward Kevin Durant], guys who can really change the game with their scoring. So, when you throw a zone at them, it kind of makes them think a little bit.”
MITCHELL AGAIN HURTS SHOULDER
Mitchell already missed eight games in January because of a left shoulder injury, and he’s now again dealing with another left shoulder issue.
Mitchell suffered a left shoulder contusion while trying to battle through a screen during Saturday’s win over the Rockets, but he was able to finish the game. He was also able to go through practice on Monday.
“It’s not as bad,” Mitchell, 27, said when asked to compare his latest left shoulder injury to the others that forced him to miss time earlier this season. “Definitely kind of like the same pain a little bit. But definitely not as bad.”

After initially hurting his shoulder on Jan. 13, Mitchell missed the next two games before returning to play in two games and then re-aggravating the injury while trying to get over a screen. Mitchell then went on to miss the next six games before returning.
“I try to play the same way,” Mitchell said when asked if he’ll think twice about battling through a screen moving forward because of his injured left shoulder. “I try not to change anything up. I mean, honestly, he just got me. I’ve been going through screens after that injury for a minute now and it hasn’t really bothered me. This time he just got me.”
When asked if he’ll play Tuesday against the Nets, Mitchell said: “We’ll see.”
The Heat hasn’t yet issued its injury report for Tuesday’s contest.
ONE DAY AT A TIME
When asked Monday what his message to the team is as the Heat works to avoid the play-in tournament with only six weeks left in the regular season, Spoelstra didn’t want to look that far ahead.
“I’m not even going to talk about that stuff anymore because that hasn’t worked for us,” Spoelstra said. “Whatever. I’ve just got to find whatever works for this group right now. Staying in the present moment is the only thing I can focus on right now with this group.”
The Heat, which has needed to qualify for the playoffs through the play-in tournament in each of the last three seasons, entered Monday in eighth place in the Eastern Conference. The Heat needs to finish among the East’s top six teams to clinch a playoff spot without needing to take part in the play-in tournament.
