Terrible foul call on Allen. Allen's standing there, and Morant is trying to squeeze through Allen and his teammate. Either offensive foul or a no call. Also, the 5 second count was really quick. The refs made it so difficult on the Cavs last 2 min of the game. Knowing the NBA's track record, their last 2 minute review's just gonna say they got it right.
BUT if you get a chance, watch that last out of bounds play again. LeVert sets a screen on Garland, and then that's it. Nothing else happens. That's the best you come up with in a critical point of the game with 3 seconds on the shot clock? You can blame the players all you want, but when your team is consistently terrible at ATO plays, it's on coaching. There's no way this crap works in the playoffs.
