I think he goes, more out of necessity rather than the fact that we don't want to pay him.
With Sullinger on the team, we are overloaded at the 4, especially if and when we resign Jeff Green. That is another reason why Danny didn't draft PJ3, it would have created a log jam at one position.
We need to free up minutes for JJJ and Sullinger, while KG still gets his 20+ at the 4. I don't see how Bass fits in unless Sully is going to play the "5" which I am fine with.
