Yes Lebron shut down Murray in the biggest part of the game. The Lakers up three and Murray drove to the bucket and hung in the air and was going to have a layup. Lebron who jumped too early wasn't going to be able to stay with him so he reached down to block the ball and instead hit Murray right on the arm. Of course after Lebron and the Whining Lakers complained to the league they ignored this foul (instead focusing on getting Jokic out of the game early in the 4th with questionable call after questionable call) and the Lakers were able to go score and effectively end the game.

So great job Lebron. You took the assignment and because you whined like a little girl even though the Lakers have gotten more fouls and far more free throws in the series you were able to foul him without it getting called.
