I think he should go overseas and play because unless an NBA team has lots of injuries I don't seem him wasting a roster spot. Sorry if you're a fan but I was never impressed with him.
Rick Brunson can still be a good third pg but i can see why the Sixers waived him since they probably want to give one of their young players a shot (Steve Smith perhaps). The Sixers do also already have Kevin Ollie who plays the same role. If something happens to one of the two Clippers point guards (Sam Cassell or Shaun Livingston) then i wouldn't really mind giving Rick Brunson a 10 contract as a stop gap pg since he is so familiar and efficient with Mike Dunleavy's coaching system.
