No one seems to be questioning whether Embiid got the shot off in time. I was wondering about it as well.
This is from Kellan Olson of Arizona Sports:
With the Suns up two and 0.8 seconds left, Chris Paul came to the free throw line for Phoenix to permanently ice out the game.
He made the first, and the second one bounced high off the front of the rim. 76ers center and MVP candidate Joel Embiid grabbed it and hucked it down the court toward the basket, somehow getting it off in time and nearly sinking the game-tying shot to go to overtime.
