Riggleman is going to do a good job of taking the Nats to a 5-10 stretch. Just stop playing the guy. He is useless and doesn't provide anything. Apparently, based of some remarks, he is negatively harming the team. I thought Rizzo was a smart guy. If he was, he would tell the Lerner Family about the concept of sunk cost, which I have to guess that billionaire businessmen understand, and how it needs to apply in this situation.
