The gd lakers just fired their gm for rejecting a Cousins trade, without clearing it with his boss; between that, and the fact that Divac admitted himself that he had a better offer three days ago, I am disinclined to believe Napear's assessment in that regard.
As to the rest, I don't see any reason to believe that, either. If so many of Cousins' ex-teammates had a problem playing with him, how come none of them are willing to put their name behind it? Hell, Nocioni was willing to put his name on it, when he spoke out about hating to play with Evans; how come nobody's willing to go on the record and say, "Yeah, I hated playing with Cousins!"
