Raptors to pacers
Andrea bargnani
Terrence Ross
Ed Davis
Toronto receives
Paul George
David West
Why Toronto?
Raptors get there small forward of the future in the Ariza-esque Paul George. We get a starting calibre power forward in return for bargnani

Why Indiana?
Ive been reading some pacers forums and Right now pacers fans are calling for Paul George's head like raptors are calling for bargnani. They get a young rookie with a lot of upside, a younger version of west in Davis and bargnani to add extend the floor.

Raptors trade
Jose Calderon
Raptors receives
Emeka Okafor

Raptors take on Okafors contract and gain a low post presence, and mentor for Valanciunas. He'd likely come off the bench.

Washington gains a pass first point guard. With wall out wizards are desperately in need of a point guard so Jose fills that hole. And when wall comes back, Washington could still use Jose off the bench.

I'm not so sure the pacers one could happen but I definitely think the Jose for Okafor could.
