Playing time hard to find for Knicks’ vet center Noah

Joakim Noah has gone from being banished by the NBA for taking a banned supplement to being banished by his own team.

For the second straight game since returning from his 20game drug suspension dating to last season, the $72 million man was inactive for Wednesday’s game and Knicks coach Jeff Hornacek doesn’t foresee an immediate change.

“We want him to be involved,’’ Hornacek said. “He wants to be involved. We don’t know when the time will come when he’s active.”

The issue is the Knicks already have a center glut with Enes Kanter as starter, Kyle O’Quinn as backup and Willy Hernangomez, a building block, fighting for minutes. Hornacek said he’s not sure he will dress four centers anytime soon.

“I’m not looking to do that right away,’’ he said.

The Knicks will need to at least showcase Noah if they have any chance of dealing him to a title contender gambling for defensive help off the bench.

The Knicks are in no rush yet to use the stretch provision on Noah. Using the stretch provision now or using it after the season would have the same consequences and cap savings. If the Knicks used the stretch provision anytime now until Sept. 1, his remaining two years of $37.8 million would be stretched across five years. Here’s the math: If they stretch him now or after the season, it would give the Knicks $11 million of extra cap room next summer and $12 million in 2019.

His cap figure would be fixed at $7.5 million from 2108-2022. If they flat out waived him without the stretch — or bought him out — they likely would get no cap savings for 2018 and 2019, but would be clear of his salary in the summer of 2020. It’s a trade-off.

General manager Scott Perry and president Steve Mills met with Kristaps Porzingis’ brother/agent, Janis, before the game, chatting courtside for about 30 minutes. The Knicks brass is trying to establish a better relationship with Janis than he had with former team president Phil Jackson.

Janis said in a Latvian magazine Porzingis is not a lock to stay in New York long-term. Kristaps repeated on a radio show the translation was “worse than it sounds.’’
