If Hedo doesn't bounce back till the trade deadline, this is what I propose:
Toronto sends: Hedo Turkoglu(10 Million per season for another 4 years) and Marcus Banks (4.5 million per season for another season)
Dallas: Josh Howard (10 Million per season that expires at the end of this season) and Matt Caroll(4.7 million per season for another 3 seasons).
Josh Howard isn't doing too well in Dallas after coming back from last season's injury and playing behind Shawn Marion so he is probably looking for a change of scenery and probably won't resign in the offseason with Dallas. Dallas may be able to live with Hedo's long term contract, if the Raptors be willing to take Matt Caroll's long contract that is half as much as Hedo while they unload Banks in the offseason somewhere.
