People are vastly overrating Posey on this board. In 22+ minutes per game last year, he averaged just 5.5 ppg on 36.5% shooting and 33.5% from three--those numbers are God awful. Add in the fact that he's not the same defender he once was and his complete existence (and contract) in NO was absolutely terrible. Though his numbers are not a ton better, Ariza's a solid upgrade (better fg% that should only improve with less to shoulder and Paul to get him the ball) over him, at this stage in their careers a much better defender, and adds stability to the wings situation in NO that they've badly needed for years. While Collison is very good, he was nothing more than a backup there so his loss is nominal for them as far as wins and losses. While I think they could get more for Collison, the facts are he didn't win games for them, they save 1.5M this year, and we may not know all the particulars just yet--perhaps they get a draft pick or something. In this regard, it makes some sense for NO though admittedly if I were them, I would not pull the trigger on the deal without a 1st rounder back from someone.
