The writing isn’t on the wall for Courtney Lee and Jarrett Jack; it’s on the bench.

For three-quarters of this season, the pair of veterans were the most reliably present pieces in the lineup — representing two of the three top Knicks in minutes played.

But now they’re outliers to the youth experiment, leaving Jack to consider the possibility of requesting a release by Thursday’s deadline so that he can join a playoff team.

“I’ve never done it before to jump from one team in the middle of the season to a playoff squad. I know that’s what other guys have done. To be honest, I don’t really know,” Jack said. “Maybe I do need to sit down and look at a list of what my best possible options are. But as of today I’m with the Knicks and want to help in any capacity I can.”

It’s an understandable emotion from a 34-year-old who has no future in New York. Jack resurrected his career this season and briefly quarterbacked the Knicks to a 17-14 record after moving into the starting lineup in October. But then they acquired Trey Burke and Emmanuel Mudiay, and Jack’s minutes transformed to nonexistent after the All-Star break with three consecutive DNPs.

Jack, who is on an expiring minimum deal, would have to be waived by March 1 to sign with a playoff team. The same goes for Joakim Noah. The Knicks have already cut two players on guaranteed deals this season — Mindaugas Kuzminskas and Ramon Sessions.
