So there's the possibility that, if, as most players do, LeBron takes a 6 year deal with an opt-out after 3 years, that LeBron might be in his final season with New Jersey before they open the building, if he decides to go with the Nets. That being the case, why not take the same deal, for more money (and an extra year), with Cleveland? If New Jersey gets its act together, he can opt out and go there once the building is built.
I'm of the opinion that *MOST* of this year's free agent class are staying right where they are, due to the fact that the Collective Bargaining Agreement talks have not been productive, and the owners are insisting on huge concessions by the players. If I was a player, I'd want my deal locked up for as long a term as I could make it, before the new CBA kicks in, when, most likely, my earning potential would be far less.
I think Bosh is moving, and Joe Johnson will consider it. Wade and James will stay put. Stoudemire will move, but only if it's to Cleveland or New York, otherwise, he'll stay with the Suns.
