The Miami Heat pulled off one of the biggest trades in franchise history, landing Giannis Antetokounmpo. But ESPN's Brian Windhorst isn't sold on an immediate payoff.

Windhorst, speaking on the *Shump Street with Iman Shumpert* podcast on July 10, 2026, compared the Heat to a team that just finished a marathon. He warned fans to keep expectations realistic for the 2026-27 season.

What did Brian Windhorst say about the Heat?

"They just ran a marathon and they're kind of breathing heavy," Windhorst said. "They may need to wait a little while before they run another marathon."

The Heat gutted their roster to get Antetokounmpo. They sent out Tyler Herro and a pile of draft picks. They also lost Norman Powell, a 2026 All-Star, to the Chicago Bulls in free agency.

Miami has roughly $13 million to $14 million in cap space left. That's not enough to sign more than one impact player. Windhorst expects the team to fill out the bench with minimum-salary veterans.

"You need to get guys on bargains who just want to come to Miami," he explained.

Why it matters for Giannis Antetokounmpo

Antetokounmpo, a two-time MVP and one of the greatest power forwards ever, now teams with Bam Adebayo. That duo is elite on both ends of the floor. But the supporting cast is thin.

Perimeter shooting is a real concern. The Heat signed Tim Hardaway Jr. to a one-year deal, but he's not a long-term fix. Without shooters, defenses can pack the paint against Antetokounmpo.

Windhorst sees the Heat as more dangerous in 2027-28 than next season. "I'm looking at them more formidable," he said. "I could be proven wrong, but I'd look at them more formidable in the 2027-28 season than in 2026-27."

What does Pat Riley think?

Pat Riley, the Heat president, called the trade for Antetokounmpo and Bobby Portis Jr. "one of the great trades in HEAT history." He called Antetokounmpo a top-five player in the league.

Riley has a track record of building winners. He turned the Heat into champions with LeBron James and Dwyane Wade. But this rebuild around Antetokounmpo will take time.

Free agency is just starting. Riley could still pull off a surprise signing. For now, though, the Heat are a team in transition.

Antetokounmpo gives them a superstar. The question is whether the rest of the roster can catch up.
