Well they are getting rid of Lee this summer. That's like the worst kept secret in the NBA. They are keeping Draymond Green at all costs, and they know they can do that without exceeding the cap if they dump Lee. Lee's still a good player who just doesn't fit on the Warriors anymore and they really have no need for him. Someone will take him off their hands. I actually wouldn't be surprised if the Celtics give them a call in case the pursuit for Kevin Love fails. Lee's a good plan B. What works out for the Warriors is that Lee's contract expires next year so it won't be that difficult to move. I also wouldn't be surprised if Philly takes him.
After that they probably have to consider moving Iggy next, but that probably won't happen until next year when Barnes is due for a new contract. Iggy might be a little harder because he's still a very useful player but is clearly not what he was back in his Sixer days. Ironically, I could see Philly taking him too.
The Warriors will be a force to be reckoned with for the next few years. I do wonder what they're going to do when Andrew Bogut breaks down for good. His skillset isn't as replaceable as Lee of Iggy.
