Last season, Pittsburgh Pirates starter Jameson Taillon pitched to a 3.20 ERA, 3.46 FIP, and 3.7 fWAR in 191 innings. His teammate Trevor Williams tossed a 3.11 ERA, 3.86 FIP, and 2.5 fWAR in 170.7 innings. At the deadline, the Pirates acquired Chris Archer in a deal that makes you stop and turn your head just out of the name they both acquired and traded away. This can lead to the question of what role is each pitcher? Taillon and Williams seemingly can be pointed to as a low one/high two based on their ERA’s and Archer has that name value, but what role do they actually serve?
