Stephen Curry drives through East “defense,” kisses it off glass (VIDEO)

MIAMI — Throughout the Heat’s playoff run, Erik Spoelstra has been confiding in and getting encouragement from another Miami coach — and it’s not Pat Riley.

Dolphins’ coach Mike McDaniel and Spoelstra have become friends.

“We’ve been texting back and forth,” Spoelstra said. “We share very similar thoughts about finding strength in adversity and using those as lessons to help you grow.”

Through that prism, the Heat have a real growth opportunity Friday night.

Miami trails Denver 2-1 in the NBA Finals heading into Game 4, and while that game is not technically must win for the Heat, it is in practice.

Getting that win means Miami finding some way to slow the Nikola Jokić and Jamal Murray two-man game. Which is what every team has tried to do all playoffs long with no success, but Game 3 was the peak of their two-man game. The Nuggets stars ran 32 pick-and-rolls in Game 3, and those plays were the heart of both getting a 30+ point triple-double — the first teammates ever to have a 30+ point triple-double in any NBA game, ever. Murray and Jokić played 40 minutes together in Game 2 and the Nuggets were +14 in those minutes (in a game they won by 15).

“I mean, the Murray/Jokic two-man game is a pretty hard action to stop,” Haywood Highsmith said. “But we got great defensive players, got some of the great two-way players in this game, Jimmy [Butler] and Bam [Adebayo], so we’re gonna figure it out. We got a lot of different bodies we can throw at Murray as well.”

That might be the best adjustment the Heat can make —throw a lot of bodies at it, sell out to stop the Murray/Jokic two-man game and dare any other Nugget to beat them. Force them to diversify the offense. Denver coach Mike Malone has been able to lean into defensive lineups because Murray and Jokić provide enough offense, it’s time for the Heat to challenge that practice.

“Whatever you do, you just can’t do it all the time,” Spoelstra said of defending the Nuggets duo. “There’s no absolutes when you get to this level. It’s the highest level of competition. You’re getting the highest level of execution. Understanding what they’re trying to get to, and we try to get them out of their comfort zones as much as possible.

“The first half, they really got to that two-man action quite a bit. They were getting a lot of traction, so they didn’t need to go to any other part of their playbook.”

The Heat need to make adjustments, too.

One adjustment they will not make is playing Tyler Herro, he has been officially ruled out for Game 4. Herro went through a brief part of the fake practice/shootaround in front of the media on Thursday, but didn’t speak to the press. Spoelstra said Herro has not yet been cleared for a game, and while there were not a lot of details it didn’t sound like Herro was all that close.

Another thing the Heat need to do is less adjustment and more effort and luck — they simply have to shoot better.

Denver’s size bothered the Heat in the paint and Miami shot just 38.2% within eight feet of the basket. The Heat also got up 35 attempts from 3 but only hit 31.4% of that. Credit Denver’s size in the paint and they’re staying home with shooters for some of that, but Miami can — and Friday night must — do better.

Which brings up an interesting question: This deep into a playoff series, is it more about strategic adjustments, or effort and just playing better?

“I think it’s a little bit of both,” Highsmith said. “It’s definitely some things we can adjust on, and then it’s also about a little bit more effort and just doing more. You always need more, always can do more… we definitely have to make some adjustments on both ends of the floor, but you know, we’ll figure it out.”

Whatever Miami does defensively, Denver will score, they have an elite offense led by a two-time MVP in Jokić. If the Heat are going to even this series headed back to the Rocky Mountains, they must find more offense.

“I mean, they, they have a really good defensive scheme. They have good defensive players,” Duncan Robinson said. “You know, for us offensively, it’s going to be about creating advantages and really putting pressure on their schemes and their players to scramble and kind of get them a motion and a lot of that happens when we’re moving the ball attacking, playing to our identity.

“We had stretches last night, and definitely stretches in this series where we’ve done it. And, we’ve definitely had stretches where we haven’t gotten to that as much as we’d like to, so we’ll continue to work through it.”

They have to work through it fast because time is running out.
