The Knicks won game 1 thanks to an insane comeback, and some diehard New York fans are already looking forward to the NBA Finals … calling out Victor Wembanyama outside Madison Square Garden!

“We want Wemby! We want Wemby!” hundreds of fans chanted outside the World’s Most Famous Arena … a place known for postgame insanity after big Knicks wins.

The vibes were clearly sky high for the Knicks fans Tuesday night … after mounting one of the largest comebacks in NBA Playoff history.

N.Y. trailed Cleveland by 22 points with less than 8 minutes left … before going on a 30-8 run to force overtime.

Once in the extra period, the shellshocked Cavs were outscored 14-3, losing game 1, 115-104, in front of a star-studded crowd that included Timothee Chalamet, Lenny Kravitz, and Dustin Hoffman.

The Spurs, like the NYK, also won game 1 in overtime, beating the favored Thunder, 122-115.

Wemby was unstoppable, scoring 41 points (on 14 for 25 shooting), grabbing 24 rebounds, and blocking 3 shots.
