Here are five of the greatest pitchers in the history of a franchise without a lot of great pitchers. They are compared using FanGraphs' method for converting FIP to WAR. The picture is regretably small, so I'll link to bigger version here and career path here. The first thing that stands out to me: Nolan Ryan was a ****ing robot. His first year in Texas was an 8.3 WAR. That may have been his best season, and I'll bet it was the best season ever from a Rangers pitcher by a wide margin. And he was 42. Ryan seems to have the peak value, but I lean towards Hough as the best Rangers pitcher ever.
