I don't think this was a basketball move. He's already a basketball legend (whether I like to admit it or not). He's going to go down as a top five player of all time, to some top 2, and to others the best of all time. He doesn't have anything left to prove basketball wise. He's going to LA to dip his hand into other markets outside of basketball and relocate with his family while riding off into the sunset these last 4+ however many years.
He wins another ring great. He doesn't, he already gets enough crap from people who hate him anyway.
