Amare Stoudemire will go into next season with $45 million left on his contract and no guarantee of a starting job.
He also could remain a reserve who plays restricted minutes.
Searching for ways to improve next season, the New York Knicks could use a reliable second scorer and dependable low-post option. They have no way of knowing if Stoudemire can provide either because of health concerns.
General manager Glen Grunwald says Tuesday that Stoudemire is a "heck of a player," but that "the question is his health and how much he can play."
Stoudemire was limited to just 29 games in the regular season and four brief appearances in the postseason because of a pair of knee surgeries.
