Smith was upset Serge Ibaka dunked with 6.9 seconds left and the game already decided. Ibaka should have simply dribbled the ball back out and allowed time to expire. Thunder coach Scott Brooks wasn’t pleased either, shaking his head and frowning. Hawks guard Mike Bibby also shouted at the Thunder bench, waving his hand in disgust.

Brooks actually was more upset with point guard Russell Westbrook, who passed to a wide-open Ibaka underneath rather than holding the ball.

“When you got the game won, you run the clock out,” Brooks said. “Russell knows how I feel about situations like that. It was a mistake.”

Kevin Durant tried to smooth things over and spoke with Smith at midcourt.

Smith also was upset about being fouled hard by Ibaka with 6:59 left in the third quarter. It appeared Ibaka’s left elbow raked the top of Smith’s head, which required some patchwork by team doctors, but no stitches.

The foul was incidental, not deliberate. Smith, however, thought he was hit by Ibaka’s teeth.

“He bit me, man,” Smith said. “I thought I needed some (stitches) … I was just in pain.”

Ibaka, the youngest player on the Thunder roster at age 21, is in his second season and learned the game in the Republic of Congo. Although it is not outlandish to think Ibaka might not fully understand the unwritten code of the NBA, Smith wasn’t buying it.

Asked if he was upset by Ibaka’s dunk, or the foul, or both, Smith said, “You know what it was. That’s showing disrespect (dunking the ball). Everybody in the whole league knows you don’t do nothing like that. I talked to Durant about it. He said he would talk to him (Ibaka) about it, and he knew that wasn’t right.

“Everybody knows that’s not proper etiquette, you know what I mean? When you’re at a dinner table, you don’t dig in first when you visit somebody’s home. You relax and see what’s going on. You check everything out before you ever get you a plate. It’s just proper etiquette. You don’t do that.

“We won’t forget that (dunk). We won’t forget something like that.”

The Thunder plays at Atlanta on March 4.
