Nope, Bron is not a counter attack player, the vast majority of his scoring comes in the halfcourt. The reason Kyrie/LeBron compliment each other is because of the fact Kyrie can play off the ball and act as a floor spacer which is something Wade couldn't do. Wade and LeBrons' games were too similar, they won off the sheer strength of talent, not because they could truly play off one another.
This Cavs team has a historically great offense, you can talk about this that and the third, but this Cavs offense has been better.
LeBron might play that way to reserve himself, but let's be real, he is best in transition...or are you saying he is better playing in a half-court set?
