Before the Nets took on the Hawks last night in Brooklyn, interim coach P.J. Carlesimo called talk of his team potentially being tied with the cross-town rival Knicks for the Atlantic Division lead with a win “meaningless.”

The Nets sure played like they agreed with him.

They made sloppy plays throughout the game and went cold at exactly the wrong time, allowing the Hawks (37-29) to open the fourth quarter with a 23-10 run to blow open the game and go on to claim a 105-93 victory over the Nets (38-28) inside Barclays Center.

“We’re not tied for the division lead,” Carlesimo said before the game. “I don’t know how you guys come up with this nonsense. They had two less losses than we do [going into yesterday’s action], so we’re not with them when they have one less loss.

“I don’t care what the numbers say ... you can’t be tied with somebody when they have one more loss than you do.

“It’s meaningless.”

It may have been meaningless to Carlesimo, but it certainly wasn’t meaningless to Nets CEO Brett Yormark, who tweeted a few minutes after Carlesimo’s comments, “Excited about tonight’s Nets game. Chance to be tied for division lead.”
