There are still more than two months before the Warriors start training camp, but power forward Draymond Green and small forward Kevin Durant already appear to have their roles perfected.

At least, off the court.

Green played hype man for Durant during a Nike event Monday night that drew a swarm of fans to Pier 48 and acted as Durant’s introduction to San Francisco since choosing this month to leave Oklahoma City for the Bay Area.

While Green was addressing the crowd, fans believing Durant might make an appearance started chanting: “Bring him out. Bring him out.”

“I’ve already had a couple of assists off him, and that’s always good,” Green said about the U.S. Olympic team’s first two exhibitions, the first games Green and Durant have played as teammates. “Hopefully, he can keep knocking down open shots.

“That’s my guy. I know people have made a big deal about our relationship, so I’m going to go ahead and bring him out.”

That’s what the crowd wanted to hear. The fans launched into a “Waaarriors” chant that transitioned into a “KD” chant.

Durant’s red hat could be seen over even the tallest fans as he approached the stage, and when they first saw his face, the chants gave way to a delirium of squeals that lasted more than a minute.

The seven-time All-Star said he wants to focus on Team USA play before he gets into the specifics of the new challenge, new city and new coach with the Warriors. He still managed to say plenty about his new teammates.

He repeatedly called the organization authentic, said the “Core 4” of Stephen Curry, Green, Andre Iguodala and Klay Thompson are refreshing in their abilities to see the big picture, and he believes they’ll all get plenty of open shots.

Durant has had some of his best games against the Warriors, including a career-high, 54-point outburst in 2014. He said he couldn’t help but notice the energy in Oracle Arena when the Thunder and Warriors met in Game 7 of the 2016 Western Conference finals, when the fans stood for the opening tip and then didn’t sit down for most of the game.

“I’m looking forward to playing in front of you guys and doing something special,” Durant told the crowd at the shoe event.

Durant, Green and Thompson will be playing for the national team against China on Tuesday night at Oracle Arena, where Durant will hear an earthquake of an ovation that makes him forget the smattering of boos he endured in Los Angeles on Sunday.

The United States has won its two exhibition games — against Argentina and China — by an average of 43 points.

“This team has really come together after Steph and LeBron (James) and a lot of those guys said they weren’t playing,” Green said. “We want to show people how good we really are. I think this is going to be one of the best U.S. teams you’ve ever seen.

“We want to smack everybody. We don’t want any close games.”

Green also predicted that the Team USA version of the KD 9 will be the shoe everyone remembers from the 2016 Olympics.

Durant was a little more modest, turning his attention back to the crowd. He and Green posed on a raised platform, allowing them to take selfies with the fans.

Before the two left, Durant picked his five favorite shoes out of the audience and autographed the pairs.

If he keeps making those types of gestures, he might not need a hype man.
