It seems the Knicks might have dragged some New York weather with them on their trip to Miami.

The Knicks made it rain for three quarters Friday, launching 34 three-pointers and connecting on 15. But the Heat weathered the storm, and by the fourth quarter Miami’s suffocating defense proved too much. Miami held New York to 3 of 9 from beyond the arc in the final period, and the Knicks managed just 18 points.

“Once [New York] started to hit a few [three-pointers], they all got into that three-point party and they all started getting into a rhythm,” coach Erik Spoelstra said. “It became contagious. It felt like they hit 30 of them.”

While Miami drove the ball into the paint in the first half, the Knicks were content to stay beyond the arc. Coming into the game, the Knicks were averaging 22.3 three-pointers per game. On Friday, New York surpassed that number by halftime.

For a five-minute period from the end of the first quarter to the middle of the second, New York shot 13 consecutive three-pointers.

“I kind of figured they were going to have a pretty good game [from beyond the arc],” Chris Bosh said. “It’s Friday night, ESPN, and one of their stars was out. It’s a chance for the guys to get more shots than usual. That can be great for some guys sometimes to get a little bit juiced up and show what they can do.”

The Knicks were just 5 of 23 from inside the three-point arc at halftime, but their 43.5 percent shooting from beyond the arc (10 of 23) put them just four points behind the Heat at halftime. And New York’s outburst came from some surprising sources. For example, Bill Walker, who had hit 16 three-pointers on the season and was shooting 32 percent from beyond the arc coming into the game, was 7 of 9 from long distance at the end of the third quarter. In the middle of the third quarter, Walker connected on three consecutive three-pointers, concluding his bombardment with a 27-foot bank shot.

Spoelstra said that in the second half he told his players to disregard the names on the back of New York’s jerseys and defend all the Knicks as though they were a certain Boston Celtics star.

“Anybody on the scouting report, whatever their shooting percentage was from behind the three-point line, you could throw that out,” Spoelstra said. “We treated everybody as Ray Allen.”

Shane Battier said the Knicks and center Tyson Chandler tend to draw teams toward the rim, thereby opening space beyond the arc.

In the fourth quarter, Miami suffocated New York’s long-range shooters by getting to the perimeter more quickly.

“In the first half we were a step slow and they got a lot of looks,” Battier said. “In the second half, we were just sharper in our defensive execution.

“A lot of times that extra step is the difference between a make and a miss.”
