James Johnson scored on his first possession in more than a month. Dragic either scored or got somebody else points pretty much every time the ball was in his hands.
As often is the case for Miami, bench guys came up big.
Dragic had 29 points and 13 assists, Bam Adebayo added 20 points on 9-for-10 shooting and the Heat — without Jimmy Butler — never trailed in a 122-111 victory over the Portland Trail Blazers on Sunday night.
“It doesn't matter for us who's playing or not," Dragic said. “We don't use excuses."
Dragic tied a career best with seven 3-pointers. Derrick Jones Jr. scored 19 points for the Heat, who got 14 from Kendrick Nunn and 12 in 22 minutes from little-used Johnson -- who was called upon largely because Miami was without Butler.
It was Johnson's first minutes since Nov. 27.
“I've been in every situation that this league can offer, honestly," Johnson said. “I know for sure it can be worse."
Tyler Herro scored 11 points for Miami, as did Meyers Leonard in his first game against his former team.
Damian Lillard led Portland with 34 points and 12 assists. Former Heat center Hassan Whiteside, booed almost every time he touched the ball, finished with 21 points and 18 rebounds for Portland.
“It felt weird at first,” Whiteside said of playing against his former club. “But a lot of them guys I haven't played with. There were a few guys out there that I actually knew."
Both teams were missing starters unexpectedly. Miami was without Butler, ruled out because of back soreness. Portland played without the services of CJ McCollum for the first time this season; he was out with an upper-respiratory infection.
“Any time one of your best players is not on the floor you're going to be less of a team,” Lillard said. “We're professionals and that's when you turn to the next guy. ... It's tough not having him but they didn't have their best player.
Anfernee Simons scored 19 points off the bench for Portland, which cut a 24-point deficit to nine in the third quarter but no closer.
“Whatever word you want to use, we didn't compete hard enough in the first half,” Portland coach Terry Stotts said. “They had us on our heels from the outset."
The Heat improved their NBA-best home record to 17-1 -- that’s only two wins shy of their home total for 41 games last season -- and are 10-0 after losses.
Heat coach Erik Spoelstra said he still roots for Whiteside, who spent five years with Miami and got traded this summer as part of the series of moves that allowed the Heat to land Butler.
“We invested a lot into him and he invested a lot into us,” Spoelstra said. “For whatever reason -- it just happens in this business -- it was just time to turn the page on that team and it’s not anyone’s fault.”
