When has KD been to a finals with a bunch of role players?
LeBron can cover a variety of roles on the court and does so very well. That allows other players to fit better in their natural roles and the teams still find success.
But fam Lebron operates a certain way that can hinder someone from their natural role. It's why people say CP3 and Bron wouldn't work since they are so ball dominant. this isn't as black and white as most make it.
