I can't really see LeBron (or Wade) leaving Miami when you consider the teams that LeBron has been talking to, and I'm sure picking up Granger and McRoberts is (if nothing else) reaffirming to him that the Heat are willing to do things to try and improve the team around him
I don't really think LeBron has any interest in playing for a smaller market after having left Cleveland and had a taste of Miami, and I'm sure it's much deeper than just basketball

Wouldn't be surprised if Bosh signed with the Rockets because he's always been the third wheel, never been given the kind of credit he saw in Toronto, and kind of tagged along for the past few years that the three have been together - I didn't look at specifics on deals from the Rockets but if they're offering him more money and better contract options then I feel like he'll probably take it

If Gasol goes to the Thunder then that's really good for them
