LeBron shot 67% when guarded by Leonard for the first 3 games. The Heat shot 28% when guarded by Leonard.
I wasn't being serious about LeBron playing great defense on him. LeBron played fine though. It was Wade's defense that was garbage in that series.
Here's Leonard's spectacular game 3, where he scored 29 points:

He hit a three pointer with LeBron's hand in his face, a fadeaway three pointer from the corner, and 1 FT (LeBron fouled him in garbage time) vs Lebron (7 points), but the rest (22 points) was against a
Miami Heat team that was completely torched by Kawhi.
