There have been a lot of 'done deals' in the past week, no? Don't believe everything (or anything really) you read/hear.
Bosh is waiting to see where Lebron goes before he agrees to any sign and trade. When Lebron signs with the Cavs the Rators will look at sign and trade packages from both Cleveland and Toronto and see who gives them the better deal. Bosh won't care which team he goes to since he will be with a true superstar. The Cavs can offer a much better deal than Miami, a deal which would include Hickson and AV(Toronto has always wanted Varejao).
Notice I said 'when' Lebron re-signs with the Cavs. You don't turn down 30 million dollars to play for another team. The Bulls seem good on paper now, but they have no one who can shoot the ball and an owner who is notorious for being ridiculously cheap. You don't go to the Knicks when they won't be getting any other free agents (Joe Johnson is getting offered the max bird rights contract).
You don't turn down even more money to play in Miami (Miami couldn't even offer Lebron a max deal if they got Bosh).
