I don't think Duncan will retire yet, he could still get another title. He has to be really disappointed after these playoffs.
Deron Williams said there are only two possible teams, the Nets or Mavericks. So look for him to go to the Mavericks since the Nets are horrible and will be for a while.
The Clippers aren't on the Lakers or Spurs level yet. The Grizzlies are still a more talented team also.
