I think it's important to note that he is coming HOME to make this decision. The Celtics are gonna be the last ones to get to him and be in his head before he mskes this decision (I hate that word now.) To a guy like Ray, I think its important that thos is where home is, and home is where the best deal is.
The fact that he is reportedly so torn about this goes to show you, the stuff with Rajon makes no difference here. It's all about him letting go of his ego and realizing he's not a starter in this league anymore. Who knows though, with Bradley out untill December (maybe,) Ray could play so well that he supplants himself back into that starting unit.
