As much as we may not like the switch-flipping of this version of the Celtics, it's hard to debate it's not real after this performance.

The Knicks, who opened their season with a blowout loss in Boston, entered Saturday night viewing their rematch with the defending-champion Celtics as a measuring stick as they approach the All-Star break.

Celtics star Jayson Tatum, who scored a game-high 40 points in the win, said he was motivated to have a big night by the sight of at least one movie star in attendance.
