I don't think this article is suggesting the Spurs got rid of Lee because of Bertans. It's suggesting that Bertans "may have made Lee expendable" but it's only the writer's speculation and not pretending to be PATFO's thinking. Lee opted out because he thought he could get more money. I hope something happens for him. He worked hard for us and I'm guessing he was a good teammate. When people opt out they are gambling.
