We could have had Cousins at an incredible value, but reportedly chose not to because of character concerns. Why on earth would we choose to add a marginal NBA talent (at this point of his career) with issues that extend far beyond the quality of his character? Heck, at least Delonte West was a likable guy.
Off the top of my head, I can't really think of a current NBA player I would want less than Matt Barnes. The thought of his presence in our locker room is frightening!
