As Embiid put the finishing touches on a 34-point explosion, he put finishing moves on the Nets and their fans. He tipped in a layup with 15.3 seconds left and never stopped jawing in Durant’s direction as both players earned technicals. After the game was sealed, the teams met at midcourt, and Embiid waved Durant and the Nets (23-10) out of the arena — a similar motion to the one Durant made two weeks ago, when he one-armed his undermanned team to victory and waved the 76ers (19-16) away at the conclusion.
