He's using the fact that he CAN leave the Heat, to put pressure on them to procure the kind of players he thinks he can win with.
If the Heat do NOTHING and he believes that he will be playing in the same lineup next season, do people think he is just going to resign and potentially finish his career on a mediocre team? I'm not sure he will sign a 6 yr. contract if he believes Beasley will be a teammate and Bosh, Johnson, etc., will still be opponents.
The same goes for Wade as goes for James- if he has so much love for their present franchise- why has he not signed already. They will get the best contract from the team they are with now...so why the suspense?
It is all power and ego from these guys, and their power comes from the simple fact that they are FAs and their teams are desperate for them to stay.
