Finnegan fills a valuable role for the Nats. He's been incredibly consistent the last three years. If you have a strong bullpen why not keep it and build elsewhere. As Forrest Gump would say, one less thing. Also, if you say he's a 7th or 8th guy, who do you think you're going to get for him that would even come close to his value. Who's going to give a top prospect if you view him as a 7th or 8th guy. Keep your strength and attack your weaknesses.
