Exclusive | Knicks turncoat who sold fanhood on eBay reveals how he feels after team won NBA championship

The once-defiant Knicks turncoat who infamously sold his “fanhood” on eBay in 2018 after too many years of agita admits he’s finally hit his limit — and that his ex-team’s NBA Finals win has him sick with remorse.Evan Perlmutter, 40, told The Post even as recently as last month — after the Knicks made it to the finals — that he had “zero regrets’’ about selling his loyalty to the highest bidder for $3,450 eight years ago and overnight switching his hoops loyalties to the Boston Celtics.But Monday — two days after the Knicks sensationally beat the Spurs to capture this year’s NBA crown — Perlmutter said he’s become a basket case and can’t hold it in any longer.“If you would have told me we’re definitely going to win one [championship] within ten years, then that obviously maybe changes things.Hindsight is 20/20,’’ the sports-marketing exec told The Post.While not admitting he had “regret,’’ Perlmutter said, “It’s more remorseful.’’Add to that “anger and disbelief.’’As friends torment him for bailing on their hometown team, Perlmutter said, “To miss being part of history sucks.”Not to be able to enjoy the moment” with childhood “inner circle” friends is “regretful,’’ too, he said.A pal acknowledged to him that the moment must be “bittersweet.’’Perlmutter shot back, “It’s just bitter, nothing sweet.”He said it’s too hard to look at his phone or even attempt to bask in the ecstatic feeling in the city awash in a sea of blue and orange pride.
