Many basketball players like to trash talk each other, attempting to make their opponents uncomfortable. It doesn’t always go well.

Grant Williams was awarded two free-throws with 0.1 second left to play in the game between the Celtics and Cavaliers with the score tied at 109.

He exchanged words with Donovan Mitchell, telling him he ‘will make both’ free-throws which would have won the game for Boston.

Unfortunately for Williams, he missed both free-throws and the game went to overtime which was won by the Cavs.
