I think this was intended to try to disrupt Golden State. LeBron has enough ego to believe that if he says he will talk to them, they will jump all over themselves to try to work that out. In so doing, players in the locker room begin wondering who has to go in order to make room for LeBron. Meanwhile, it puts a bit of pressure on Gilbert to make a move now to make the Cavs competitive this year--sign Monroe maybe?
I don't think its going to work. The Warriors are scoffing at the idea and Warriors mgmt just needs to come out and say "we like our team how it is, thank you."
Besides all of this, LeBron is a drama queen. He loves to be the center of attention.
