Yeah, I knew Jarvis wasn't very good, but the negative WAR and career ERA over 6 were still pretty striking. Not sure how he hung around for 12 years - he never had one of those flukey good years that can keep a player in the league for years (he was kinda sorta OK in 2001, but that was his career highlight), and it's not like he was some elite prospect with a great draft pedigree.
