Hold on a sec. It's not totally impossible for the heat to get all three between Wade/Bosh/James.

"MC" is max contract. The heat have been absolutely unloading for a while now (I think they only have five players under contract for next season, or something to that extent). While it is unlikely, it's not too unreasonable to suggest that each of the three take a 12% pay cut (2.64/3) in order to play together on a superteam. Especially since beasley is a potential bargaining chip in a bosh sign-and-trade.
I didn't hear that Bosh had denied this possibility; it was my impression that there was a "free agent summit" between the three where this scenario was discussed, maybe at their Stonecutters meeting. I love NBA rumors.
