If that is the case, then why would the Sox take on the larger deal of Robbie Ray in the first place? And if they did, do you think they pay arbitration raises to all of Houck, Crawford, Casas, Duran and Winckowski? If not, who goes and how does replacing that player with Robbie Ray help at all?
Probably also worth noting, those 5 players represent the status quo, not a difference. The Sox came to an agreement with most of their arbitration cases this past year...
