BC turned down a draft day deal with ATL for Childress and the 11. Caldy was a borderline NBA starter then. He improved exponentially this year. Its a no brainer that he would be an ideal fit in Portland. He doesnt need the ball in his hands most of the team, he can shoot the ball, lead a team and he is still relatively young. He would be deadly operating in Portland with the return of Oden.
No point in the Raptors trading up to 13 from 17 in this deep draft. So I dont really see anything could change BC's mind otherwise.
