Who will blink first?

The contentious relationship between Knicks superstar Carmelo Anthony and team president Phil Jackson has reached critical mass, according to reports.

Nine-time all-star Anthony, who Jackson has taken subtle shots at on Twitter two days ago, might opt to invoke that clause and wait to see what Jackson career moves might be. Here is Jackson’s wily tweet (his first in a long time) on Tuesday.

The Zen Master has an opt-out clause available to him at the three-year mark of his contract, although it’s not known whether that kicks in on March 19 (his three-year anniversary), or at the end of the 2016-17 season.

Anthony, for his part, has said he is open to being traded to a contender — the Clippers and Boston being two of them — but has also stated he loves New York, even though he owns a second home in L.A.

Jackson’s passive-agressive tactics have only reportedly made Anthony want to stay in the Big Apple even more.

Anthony is under contract past 2017-18, with a player option of just under $28 million in 2018-19. He’s currently averaging 23 points, 6.1 rebounds, and 2.9 assists in his sixth full season with the Knicks, who sit 12th in the Eastern Conference at 22-32 after Wednesday night’s 119-115 loss to the Clips.
