Josh Smith + Zaza Pachulia + 1st round pick for Chris Bosh
The Hawks get the second scorer that they sorely need to place alongside Joe Johnson ... and become a legitimate contender in the East. A team capable of winning an NBA title.
I think this is only a suitable trade for Toronto if they're convinced Chris Bosh is leaving or very likely to leave ... in that case it gives them an established player, a borderline All-Star, who is young and has potential for a lot more. A solid backup big in Zaza. And a first round pick.
