ATLANTA -- On the Heat’s last trip here, LeBron James and Dwyane Wade were out with injuries. It took three overtimes for Miami to dispatch a Hawks team that led for much of the game.

The question remained what the Heat could do to Atlanta at full strength.

It’s a question no longer.

Miami dominated the boards and pretty much every other aspect of the game, with James and Chris Bosh combining for 29 rebounds and both posting double-doubles, while Wade added 21 points.

Not helping the Hawks’ cause under the basket was the absence of forward and former University of Florida star Al Horford, who has been out since Jan. 11 with a torn pectoral muscle, which required surgery.

In the first matchup with the Heat in Atlanta, he had a double-double in 40 minutes before fouling out, helping the Hawks keep close to Miami in rebounds, 56-51.

But without Horford, Atlanta had no inside or rebounding presence to speak of, losing the rebounding battle 52-38, and that was after a fourth quarter when Miami pulled most of its starters.

“It’s always going to be different without an All-Star,” said Bosh of Horford being out.

“But we have to take advantage of that. They still have good talent; they have a deep team. We just played a good game [Sunday].”

That seemed to be the consensus among the Heat players, with James agreeing with the assessment that this was their “A-plus game,” and coach Erik Spoelstra saying the team played the way he expects on both ends.

That was especially true in the rebounding department, where Spoelstra said his players’ aggressiveness and technique was key to having a significant edge.

“We got ourselves in front of the ball the majority of the night,” Spoelstra said.

“If we’re pulling a lot of triggers and taking our bodies off of them, we’re out of position.”

The biggest addition on the rebounding front for the Heat this time was James, with his 13 rebounds in 30 minutes. James did not even take the floor in the fourth quarter.

His 6-8, 250-pound frame is always tough for opponents to keep away from the ball when it’s loose. But James seemed particularly aggressive on this night.

He said his focus on controlling the misses not only keeps the ball away from opponents but also feeds into the way this team wants to play offensively.

“I wanted to rebound [Sunday night] because it enables me to push the tempo,” James said. “We’ve got to clean glass. We held a good-shooting team to 38 percent, and we were able to clean glass and get out and run. That put a lot of pressure on their defense.”

It’s been one of the focuses all season, and it’s been successful against the Hawks, against whom the Heat has had its two highest rebound totals of the season — 56 and 52.

“We kind of think about that every time we take the court,” Bosh said.

“Rebounding is always important. We don’t want teams getting second-chance points and deflating our defense. And LeBron, nothing really surprises me about him anymore. He’s athletic, and he goes up and gets the rebound.”
