After Wednesday night’s final buzzer, the public address announcer told the crowd that Mavericks coach Rick Carlisle had just won his 500th game, 105-99 over Portland at American Airlines Center.

It’s a significant milestone. Carlisle (500-353) is just the 28th coach to reach it. There have been 299 head coaches in NBA history, so Carlisle is among the top 9.4-percent of his profession. Carlisle became the 11th-fastest coach to reach the 500-win milestone, doing so in his 853rd game.

“It means I’ve been around a long time; I’m getting old,” said Carlisle, who actually is only 53. “But it means I’ve had a lot of good players. It’s meaningful, but I’m not into those kinds of things. I’m into the day-to-day stuff.

“One relief I have is I think after tomorrow, I won’t have to hear about it again for a while, so that’s good.”

When Mavericks players and the coaching staff reached the locker room, the players gave him a standing ovation. It’s been a difficult season for Carlisle, whose Mavericks are 21-28. The only time one of his teams has finished below .500 was in 2006-2007, when Indiana finished 35-47.

“I’ve seen a side of him this year that I’ve never seen before,” forward Shawn Marion said. “I’ve seen him do stuff that I’ve never seen before. This has been frustrating for everybody.”

Seen him do things like what?

“It’s a little aggressive, a little in your face to a certain degree _ and it’s cool. It’s kind of cool.”

Added Dirk Nowitzki: “He’s gotten in people’s faces, which I haven’t seen in the first couple of years. He needed to be tough on those younger guys and he definitely was.

“If you lose, sometimes coaches are more intense. Sometimes you’ve got to be harder, you’ve got to coach harder. . . . He was hard on O.J. (Mayo) and (Darren) Collison, teaching them every day. They both, I thought, took major leaps. You’ve got to give them credit. They hung in there. They were coachable.”
