NEW YORK — This was the most glorious basketball night in Madison Square Garden history, made possible by an NBA Finals comeback like no other, by a crowd that just would not quit, and by a stunning midair play from OG Anunoby that no other New York Knicks player could have made.Not Willis Reed, Patrick Ewing, Dave DeBusschere, Bernard King or Carmelo Anthony.Nobody.In the final seconds of Game 4, Anunoby swooped in while tracking Jalen Brunson’s deep miss, Superman style, and went flying above the San Antonio Spurs players who forgot to put a body on him. The uber-athletic 6-foot-7 forward was thinking of executing a right-hand follow dunk, but the rebound didn’t cooperate. It was over his head. Anunoby could get a piece of the ball only with his right fingertips, which deflected it toward the goal, through the net and into a forever place in NBA lore while he crashed onto his rump and slid out of bounds.The World Cup is here, so why not call OG’s a “hand of God” play? His coach, Mike Brown, argued that it was “bigger than any other play in the history of Knicks basketball.”Jerry Seinfeld was among the 19,812 witnesses who had that look on their face best captured by Jack Buck’s immortal call of Kirk Gibson’s homer in the 1988 World Series:I don’t believe what I just saw.The crowd went wilder than it did when one of the spectators, Larry Johnson, made his famous four-point play in the 1999 Eastern Conference finals. I was there that day. I was also at the Garden in 1994 when Ewing sent the Knicks to the finals, stood on the scorer’s table and wrapped his extended arms around the city.This comeback from a 29-point third-quarter deficit, and OG’s OMG finisher with 1.2 seconds left in a 107-106 victory, defined the greatest event I’ve ever attended in the Garden, hands down. The Knicks left the building with a 3-1 series lead. They are 48 earnest minutes of basketball away from their first championship since 1973.Hugs and kisses and tears all around. If you weren’t a member of the Spurs’ traveling party and you didn’t have goosebumps, you should have checked immediately for a pulse.Two nights after they kicked away a chance to sweep San Antonio like they had swept Cleveland and Philadelphia, the Knicks were all big winners for the 14th time in their last 15 postseason games, everyone from Anunoby to Brunson to Karl-Anthony Towns to Jose Alvarado.But only one Knick amid the celebration had the nerve to essentially guarantee the victory. And he was the one member of the home team who had the most to lose.‘We will win’James Dolan grew up on Long Island wanting to be Joe Namath. All these years later, as the billionaire baron of the Garden, Dolan was feeling comfortable enough about his Knicks’ title chances to pull a Broadway Joe on WFAN Radio’s “The Carton Show” fewer than five hours before tipoff. A sample of what he said:
