Lillard is a better shooter? That's debatable.
The last 4 seasons Kawhi has a 48FG%, and for his career has a 38 3P%
In the last 4 seasons Lillard has 43FG% and for his career has a 37 3P%
In the playoffs Kawhi has a a career 51FG% and 42 3P%
In the playoffs Lillard has a career 40FG% and 34 3P%
Overall though, I agree with these rankings.
I think lilard takes harder shots, kawhi is more of a spot up shooter, lilard shoots more off the dribble and from farther away. As a pure shooter, I think lilard is better, but kawhi is a smarter offensive player and has the advantage of height and strength
