Watch: LeBron shows utter lack of respect for Olynyk's defense

Kelly Olynyk may have played the hero for the Boston Celtics in Game 7 of the East Semifinals, but the conference finals are a whole other beast.

LeBron James let him know that.

Olynyk picked up James on the perimeter early in Game 1 of the ECF, and it didn't go well. The Cleveland Cavaliers superstar straight up stunted on the Canadian center, casually dribbling between his legs and even turning his back on him before driving to the hoop for an easy layup.

We've seen this lack of mercy from James before in these playoffs, but man is it fun ... unless you're rooting for the opposing team.

James finished with a game-high 38 points on 58.3 percent shooting from the field to go along with nine rebounds, seven assists, and two steals in Cleveland's 117-104 victory at TD Garden.
