“Sell the team”? Nope.

Fire the president? Yep.

Owner James Dolan axed team president Steve Mills on Tuesday amid another brutal season in which the Knicks are 15-36 — and he did it just two days before the trade deadline.

General manager Scott Perry will take over basketball operations but is on thin ice. Mills — who has had a hand in so much of the Knicks’ misery over the past two decades — is expected to become a board member for a new sports company Dolan is weaving. It will not be the MSG board.

According to sources, Raptors team president Masai Ujiri still will be at the top of Dolan’s wish list. However, Ujiri is under contract through next season and will require compensation — such as at least one first-round draft pick.

Dolan’s first attempt at Ujiri after firing Phil Jackson was squashed because of Dolan’s reluctance to give up major compensation and that could be the case again. The Post has reported the NBA prefers Ujiri in New York rather than Toronto. Dolan is said to also be enamored with hiring a prominent agent — which was the model in Golden State (Bob Myers) and with the Lakers (Rob Pelinka).

The firing comes just six days after fans chanted “Sell the team’’ late in a blowout loss to Memphis that contained a brawl between players from both teams.

“Steve and I have come to the decision that it would be best for him to leave his role as president of the New York Knicks,” Dolan said in a statement. “We thank Steve for his many years of service to our organization and look forward to continuing our relationship with him as part of our board.”

Mills rejoined the Knicks as president in 2013 — just two days before training camp began — and was fired two days before the 2020 trade deadline. Mills, a former point guard at Princeton, originally joined forces with Dolan in 2003 as the CEO and sports business president of MSG. He left in 2009 to work with Magic Johnson Enterprises.

According to a source, Perry and Mills had a divide over trade issues with the deadline approaching. One point of contention was said to be Marcus Morris — whether to trade him or attempt to re-sign him this July. ESPN has indicated Perry pushed to collect assets in exchange for Morris.

Sources have also indicated Mills and Perry were not on the same page early last year when it came to drafting RJ Barrett at No. 3. Mills was more open to trading down to accumulate assets before acquiescing.

Only Perry made the trip to Cleveland to witness the Knicks’ overtime victory over the Cavaliers on Monday night, their second straight win.

The Post reported last week members of the front office feared Mills or Perry would be fired soon after the trade deadline.

“Dolan is his friend, but even he knows he did a bad job,’’ one NBA source said.

Mills was promoted to president when Phil Jackson was fired after the 2017 season, and his first move was signing Tim Hardaway Jr. to a $71 million contract.

However, Mills’ failure to placate Kristaps Porzingis and ultimately trade him, essentially for cap space and Dennis Smith Jr., was also part of his undoing. The Knicks cap space did not help them land Kevin Durant and Kyrie Irving as they had hoped.

“It has been a great honor to represent the Knicks,” Mills said in a statement. “I will always be grateful to Jim for giving me the chance to represent this franchise and I’m disappointed we were unable to achieve success for New York. I would like to thank the staff and the players for their hard work during my tenure. I will always be a Knicks fan.”

The Knicks also have decisions to make whether to continue pursuit of D’Angelo Russell and his $117 million contract in a deal with the Warriors. According to a source, Mills — not Perry — was talking to the Warriors.

Earlier this season, the Knicks fired head coach David Fizdale and installed Mike Miller as interim coach. The Mills-Perry decision to go with Fizdale over Mike Budenholzer before the 2018 season proved a colossal mistake — one of many made by Mills.

The Knicks had the worst record in the NBA (178-365, .328 win percentage) in Mills’ six-plus seasons as either the team’s GM or president. He was hired right after a 54-win season, making his second stint even more regrettable. The Knicks will miss the playoffs a seventh straight season.
