I've been wondering this for a while. I would hope that was part of the pitch to a Free Agent because it's a truth.
However, I think players do not want to play LeBron and so that might definitely be a discouraging factor. Not saying everyone is afraid of him but I think that's true. Durant got smashed by him in the Finals before.
Washington is very appealing though for many reasons so I keep seeing the appeal for Durant. I would love to see Wall/Durant with Beal. I would like if that happened to balance things out and of course we can benefit by the same logic.
