So I just went back and watched the entire game.
Lebron went one on one four times in the game, not counting post ups. Two were against Duncan and one was against Aldridge. The two post ups were against Kawhi, with one airball and one non-shooting foul. Lebron probably scored between five and nine points in the entire game with Kawhi checking him, three of them on a jump shot that he took off the dribble because Kawhi hadn't set up yet. Lebron scored on a layup in a two man game with Kawhi fronting him, and Lebron scored another layup on an offensive rebound. Lebron got past Kawhi without a screen in the final minute of the game and drew two defenders and dished to Thompson for a dunk. Most of the game was pick and roll, with teammates throwing screens at him so frantically they were sometimes coming two at a time. Even with a lot of help, Lebron's offense was nearly nonexistent with Kawhi on him.
Lebron casually went through everyone to dunk the ball precisely zero times in the game. One on one, Lebron blew past Kawhi precisely one time in the game, down ten with less than a minute to go. Lebron got past Kawhi several times in pick and roll, and Kawhi's help picked Lebron up, just like Lebron's help set the pick on Leonard. On one of them, Kawhi recovered and blocked Lebron's shot, on another, Lebron got all the way to the basket and got a phantom foul call. Tough row to hoe with Kawhi checking you.
Dismissing Kawhi's defense saying "he had help" in pick and roll is beyond re ed, as pick and roll requires an offensive player to have help.
