(Sorry for multiple posts) Why does everyone think Arrieta will have to settle for a worse contract than Darvish? Granted Darvish had a slightly better 2017 season, especially after getting traded, but from 2014-2017: Arrieta: 119 GS, 751 IP, 2.67 ERA, 3.04 FIP, 3.25 xFIP, 18.5 fWAR Darvish: 70 GS, 431 IP, 3.48 ERA, 3.33 FIP, 3.31 xFIP, 10.0 fWAR Darvish is only five months younger, has been far less durable, and a worse pitcher.
