Some things never change, no matter the season.

Greg Monroe quietly producing a double-double.

John Mason belting out “Deee-troit basketbaaaall!”, whether there’s a full Palace or half-empty building.

And Chauncey Billups settling things down the stretch and hitting a couple of backbreaking 3-pointers to help the Pistons pull away.

It was like Billups never left, as Pistons fans chanted “MVP” with him at the free-throw line with less than two minutes remaining. He only had 14 points at the time, but all of them were crucial as the Pistons began their 2013-14 season with a 113-102 win at the Palace in front of an energized crowd.

He exited with 18.7 seconds left, with 16 points, five assists and three rebounds — and received a standing ovation from an appreciative house.

With the Pistons clinging to a seven-point lead after leading by 15 early, Billups hopped and stepped into a rhythm 3-pointer. Then after Josh Smith drew a charge, Billups sensed the momentum was there for the taking.

Pistons coach Maurice Cheeks called the former basket a “composure shot,” and with that in mind, perhaps the latter was the “Let’s go home shot.”

“I’ve seen him do it many times before against me,” Cheeks said. “Chauncey said it in the huddle, they would make a run, and let’s stay composed.”

With no hesitation, he unleashed another 3-pointer with 5:39 left, and even though the Wizards kept it within a reasonable margin afterwards, he shut the door on the game — as the Pistons drew their first blood of the season against an opponent many believe they’ll battle closely with for playoff status.

If it weren’t for the Pistons’ 19 turnovers, and their leaving Wizards forward Trevor Ariza open for 3-pointers (six of them, 28 points) the spread could have been larger as they shook off early nerves to jump on the Wizards.

They harassed the Wizards backcourt of John Wall and Bradley Beal, as those two combined for 38 points but it took 39 shots to achieve it. Beal missed four of his six 3-point attempts, while Wall missed all four of his.

Cheeks will take Ariza having an out-of-body night if his players are sticking to their principles.

“I don’t think we were overhelping. We want to clog the paint and make them make 3-point shots,” Cheeks said. “We challenged the shots. Ariza made them. We want to keep it out of the paint and hopefully they’ll miss them.”

The debut appearance of the Monroe-Smith-Andre Drummond front line was productive, as they dominated the glass and put their stamp on the game.
