James Harden and Kenny Atkinson go at each other on the sideline as the Cavaliers fall to 4-4 after two losses to Oklahoma City

James Harden and Kenny Atkinson went at each other on the sideline in the second quarter of Wednesday’s loss at Oklahoma City, and the clip circulated all day Thursday as the Cleveland Cavaliers sat at 4-4 after being beaten by the Thunder twice in three nights. Atkinson yelled from the bench. Harden, standing in the free-throw lane during Shai Gilgeous-Alexander’s free throws, yelled back. Both men threw their arms out. The Cavaliers were down by 22 at the time, right after a Harden turnover that had sent Gilgeous-Alexander the other way for the foul.

What the exchange looked like

The moment came late in the second quarter at Paycom Center. Harden had just turned the ball over. Gilgeous-Alexander was fouled on the break, and while he shot free throws Harden was one of Cleveland’s rebounders. Atkinson shouted something from behind him. Harden answered. The two kept going for several seconds, voices up and arms out, before the game moved on. Cleveland still trailed by a large margin at the half and finished on the short end of a 124-116 score.

What Atkinson said afterward

Atkinson did not address the exchange in his postgame availability. He blamed the first quarter instead. Oklahoma City led 37-20 after one and by as many as 25 in the second. “You can’t come in on the road, especially against a really good team, and, you know, five turnovers,” Atkinson said. “I think four of them were live ball.” He said Cleveland went 2-for-9 from three in the first while Oklahoma City went 6-for-10. “The combination of turnovers, make or miss league, you know, that’s how the big separation happened.”

He also took the positives from a second-half push. Cleveland outscored Oklahoma City 72-64 after halftime and got within six late on three straight threes from Donovan Mitchell. “Give the guys a lot of credit for fighting back, keeping our composure,” Atkinson said. “You’re in a situation like that, especially on the road, you could fold.” He still called the result disappointing: “Three quarters really solid play, and you have one quarter where you’re not up to par.”

Where the Cavaliers stand

Harden finished with 19 points on 5-of-16 shooting. Mitchell led Cleveland with 27. Evan Mobley had 16 points and 10 rebounds. Jarrett Allen left in the first quarter with a right-knee injury and did not return; he later said he was “alright,” and our injury note has that update. The Thunder’s Gilgeous-Alexander scored 42, two nights after his 43 and a go-ahead three beat Cleveland 117-112 in Cleveland.

The Cavaliers are now 4-4 and have lost three of their last four. Harden is in his first full season in Cleveland on a three-year deal after re-signing last summer. Atkinson is in his third season as head coach. Neither has publicly described what was said on the sideline. The next tests are at home: Philadelphia on Friday night, then the Knicks on Saturday, after a week that opened with consecutive losses to a Thunder team that is 6-2 without three long-term starters.

A heated exchange mid-game is not unusual in the NBA, and one clip does not decide a season. What it does is put a spotlight on a team that has not looked settled through eight games, and on the relationship between its coach and one of its veterans as Cleveland tries to climb back toward the East’s top tier.
