I get what you are saying , but to me the difference in samples in the playoffs makes keeping the ball out of play that much more important . We are talking 3 / / 5 and 7 game series . Not a lot of margin due error.
I know the Cubs defense is elite , but even they make mistakes and when the ball is put a lot in play bad stuff can happen , it’s just the way it is .
Alcantara is not bad . His fíp and xFIP are just a touch over 4. His xera is 3.75 however . He is okay , but I feel he is a bit overrated in general . I take him but not really sure what I would give up
With that said , after looking closer at Detmers o am not sure I give up Rojas for him . There seems to be some sort of risk with every pitcher except Skubal
