The Heat set the tone early by jumping out to a six-point lead after the first quarter.
The second quarter was going slow, and Dwyane Wade had yet to score around the three-minute mark.
Then he hit a jumper. Then another. He was feeling it.
So he went behind the arc and took another. And another. And one last one.
All swishes. When he was done he had scored 13 points and staked the Heat to a 13-point lead they would not relinquish the rest of the game.
So what changed?
The role players started playing their roles. Wade's 35 points were not the surprise of the night, but Daequan Cook's 20 points were.
Cook had struggled since the three-point competition at the NBA All-Star Game in February.
But against the Hawks he went for six three-pointers. Wade also hit six three-pointers as they became the first teammates in NBA history to both have six treys in one game.
Jermaine O'Neal also stepped up with 19 points; Udonis Haslem and Michael Beasley both ended up in double-digits as well.
These were not the same Heat that lost by 26 points to the Hawks just days ago.
These Heat were able to limit the Hawks bench to 20 points while their own scored 37.
Other noticeable numbers were the Heat's shooting percentages. 55 percent from the field and 57 perecent from three point range. How many times do you see a team shoot threes better than two's?
Just to demonstrate how good the Heat's shooting was, Wade banked in a three pointer as the shot-clock expired. It will surely be on the top 10 tomorrow.
Now the Heat will head back to Miami, having won their first game in Atlanta all season, and having stolen home-court advantage from the Hawks.
Win out at home and we can watch LeBron and Wade battle it out in round two.
