Bosh is just as an untouchable as BD is. There is no way Toronto would give Bosh away unless he wants out.
I don't think this rumor had any leverage anyway, and I first heard it I certainly dismissed it. Toronto has been saying for months that they would not trade Vince Carter unless it brought in another NBA superstar or made the team substantially better. As much as PJ and Maglorie are good role players, they are not superstars, and would not make a team desperate for offense any better at all....In fact, it gives them less offensive output. Although VC has been hurt, he is one of the most popular players in the league, probably the best dunker, and extremely valuable to the franchise that holds him.
