Notes: KG at center; Johnson's hot start

NEW YORK -- Kevin Garnett is playing center for the Brooklyn Nets ... albeit reluctantly.

“It’s not my preference, but it is what it is, and whatever we have to do to win, that’s what it is,” said Garnett, who was in a laughing mood following the Nets’ 104-95 double-overtime victory over the Miami Heat on Friday night at Barclays Center.

“I should’ve put that s--- in my contract. You can tell [coach] Jason [Kidd] I said that.”

Garnett, who has played power forward for the majority of his 19-year career, has had to move to center with Brook Lopez out.

Friday night, Garnett, 37, recorded his first double-double of the season -- 12 points and 10 rebounds in a season-high 36 minutes.

Joe Johnson was asked about his 22-point first quarter.

“First, my body was feeling good,” said Johnson, who hit his first eight shots and finished 9-for-10 from the field in the opening stanza.

“I just came out trying to be aggressive, not just on offense, but on defense as well. I was really trying to get to the basket, get a couple post-ups, and the 3-point line opened up a little bit and I just made a couple of 3's.”

• As it has been throughout their season-high five-game winning streak, defense was key for the Nets. They held the Heat to just 42.5 percent shooting, Miami’s second-lowest field goal percentage of the season.

The Heat entered Friday night’s game shooting an NBA-best 51.2 percent.

The Nets have yet to yield 100 points during the streak.

The Heat went 3-for-13 in the two overtime periods and scored six total points. They became the first team in the shot-clock era (1954-55) to score six overtime points or less in a game that went at least two overtime periods.

LeBron James got his -- scoring a game-high 36 points -- but that was fine. Miami went 6-for-23 from 3-point range.

“With LeBron out there, it’s hard to just keep him out of the paint,” Kidd said. “He makes so many right plays and finds his teammates. For us, one of the things we talked about is taking away the 3 and making sure that they didn’t knock down a lot of 3s. Defensively, I thought we were solid.”

Paul Pierce (23) notched as many as 20 points for just the third time this season. Pierce had 16 of his 23 after the first three quarters.
