He left w/o getting Cleveland a ring and he said that was his goal; so that reflects on him: commitment, etc. Also, his vanity and selfishness showed when he allowed all those people to come in and kiss his a$$ to make an offer and you know he had his mind made up already despite what he says. Also, the fact that he $crewed the Cavs out of any change of signing a good free agent while they were waiting for him. Bad all around.
Yeah, I've speculated about that, as I'm sure have others. What would have been the consequence of their winning the whole thing? I'm assuming he would have looked ridiculous leaving after that, so, if that was the position he was in... get a little injury on your arm... nothing too serious... just enough to throw you off... pun intended.
