Assuming Bosh can get cleared I have no idea why he would come to Boston. Boston isn't a Chris Bosh away from a title. I would expect that he would go to a contender or a place where he has friends or comfort. I would think Cleveland would be the most likely destination. A real contender, he has a friend there, and while Bosh would have a large role, he wouldn't be counted on night in and night out so he can take games off if he needs to regulate his medicine, doctor's appts, etc. Cleveland also has one of the best hospitals in the world so he can continue to get great care (I realize Boston and other places also have great hospitals, but those places don't have Lebron James and aren't real contenders).
