Miami Heat clamp down on defense to destroy New York Knicks as LeBron James ties Oscar Robertson

Miami, spurred by a 36-8 run in the first half, led by as many as 26 points and held on rather comfortably.

The Heat snapped the Knicks' four-game win streak, holding them to 32-percent shooting from the floor.

"They are a good defensive team, that's one part of it -- they make it difficult for you to score," Knicks coach Derek Fisher said when asked about his team's offense's futility.

"Offensively we weren't as organised. We were trying to take it to them instead of reading the defense and seeing what was available."

Miami got 16 points each from guard Dwyane Wade and forward Chris Bosh. No-one has scored more than 30 points in a game all season for the Heat.

"It's just about the team -- it's not about the numbers," Wade said of the unimpressive offensive statistics.

Heat center Hassan Whiteside had 11 points, 11 rebounds and a game-high five blocks, while point guard Goran Dragic added 13 points, nine rebounds and five assists.

"It was fitting that there wasn't a quote-unquote star of the game," Heat coach Erik Spoelstra said.

"It was more of a group effort. Our defense was probably our best of this homestand."

The Heat cooled off the Knicks but not rookie power forward Kristaps Porzingis, who scored 20 points, pulled in a game-high 14 rebounds and made two blocks. It was his seventh double-double of the season.

Knicks forward Carmelo Anthony led all scorers with 21 points and added eight rebounds.

Miami's reserves totalled 30 points, including 12 from guard Tyler Johnson, who said there was a reason why the Heat defended so well against New York.

"It was the communication," Johnson said. "You could hear everybody talking."

New York could only get as close as 12 points in the fourth quarter as Miami's relentless defense meant they were never really threatened.

"It's not easy defending in this league," Spoelstra said.

"There are so many good, talented offensive players and teams, and the way they spread you out now, it takes a full team commitment."

LeBron James joined Oscar Robertson's elite company while Kevin Love scored a season-high 34 points in the Cleveland Cavaliers' 117-103 win over the Orlando Magic.

James joined Robertson as the only players in NBA history to rank in the top 25 in both scoring and assists.

James' assist on Love's three-pointer with five minutes left in the second quarter gave him 6,387, moving him ahead of Norm Nixon and into 25th place.

James is 19th on the all-time scoring list with 25,274 and should pass Reggie Miller (25,279) for 18th on Wednesday at Toronto.

Robertson ranks 11th all-time in scoring (26,710) and sixth in assists (9,887).

Forward Andrew Nicholson scored 18 points off the bench and center Nikola Vucevic had 12 points and five rebounds for the Magic, who rallied from an early 12-point deficit to take a 42-34 lead in the second quarter before Love got hot.

Elsewhere, there were victories for the Oklahoma City Thunder (who beat the Utah Jazz 111-89) and the San Antonio Spurs, who eased past the Phoenix Suns 98-84.

Monday night's other games saw the Philadelphia 76ers go down 100-95 to the Minnesota Timberwolves and the Charlotte Hornets beat the Sacramento Kings 127-122 after overtime.
