I'd hope to Portland as he would fill a need at the back up PF or maybe even a larger line up playing at the three. Chicago needs a big, not so sure Utah loves Boozer, maybe Utah would be interested in keeping Millsap and getting a trade exception, appears that Portland is forcing Utah into making a trade, maybe something like this?
UTA Sends: Carlos Boozer to CHI
UTA Receives: Jerome James or Tim Thomas (both expiring) + Trade exception (from our salary cap)
POR Sends: Steve Blake to CHI, Travis Outlaw to CHI, Trade exception (from our salary cap) to UTA
POR Receives: Kirk Hinrich, Ty Thomas
CHI Sends: Kirk Hinrich to POR, Ty Thomas to POR, Jerome James or Tim Thomas to UTA
CHI Receives: Carlos Boozer, Steve Blake, Travis Outlaw
Hinrich, Bayless
Roy, Rudy
Batum, Webster
Aldridge, Thomas
Oden, Przybilla
Sprinkle in some role bench players, still a decent second unit for Portland.
