If we assume from Sekou's blog that Detroit is the powerhouse in the East, maybe a Billups, Prince, Amir Johnson for Smith and Bibby.
Detroit gets a future all star who fans will love in Detroit and get a big expiring contract in Bibby.
The Hawks get an upgrade at the point, gain more depth, and perhaps get a young stud in Johnson. Marvin can move to 6th man or against certain lineups the Hawks could feature Prince and Marvin at the forward positions.
Thoughts? Only reasonable SnT that I can come up with.
