I think Smith is still upset how he's been snaked from the All Star Game. I totally agree how the Hawks sohuld totally start rebuilding. Johnson is starting to age slowly now, and injury is getting to him. Though he's a solid player I thought the max money was too much.
However I wouldnt mind this trade though:
Raptors get: Horford And Patterson
Hawks get: Ed Davis, Barbosa, Budinger thabeet and Dalembert
Rockets get: Josh Smith, Gary Forbes and Raptors
2013 1st, 2012 2nd
Not sure if its a solid trade, but Ill say it works out for all 3 teams in some way
