Completely valid. We’ve generally been lucky with SP health, but can’t assume that continues. On a non-payroll constrained team - I don’t think there is need to flip Luis. But square peg, meet circular hole…

Sign Roki. Flip Castillo to Red Sox for Casas (and whatever evens the value), given Red Sox needs for pitching. Sign Turner for DH/3B depth. Castillo trade opens up payroll to sign additional 2B/3B. That’s the pipe dream
