The thing to remember is that while he clearly wanted to go "home" last year, that was with the only pro organization and city he had known being the San Antonio Spurs. Living a year in Toronto and playing for the Raps has to have significantly changed his perspective on things. There's no way it hasn't. The Raptors have no question marks for him to worry about - they've proven that they're a first class organization, with first class medical and training departments, with first class people running the show, with first class super talented team-first championship-calibre teammates, and a first class city to play in.
There is no way he would pass up this opportunity to hear the best free agency pitches he can before making a final decision, but I have a very hard time seeing anyone beat the Raptors' pitch at this point. Not even the clippers, given that LA isn't even his home anyways.
