How would he give up 3M? The Spurs could have very well said to him: "Look, we would like for you to push back your deadline. We love you and we really appreciate everything you have done for us. However, because of the direction we are going, we are going to waive you since your contract is only 1M guaranteed. If you push back that date a few weeks, we will still get you your 1M plus some extra money for your troubles, but it would really help us out. If not, we understand and we will waive you by June 30th".
