Porky and Wacha were originally slotted in as 5th-to-7th options, of course. But the team did more than lose Wheeler. Syndergaard's elbow blew, Stroman's commitment blew, and Matz' pitching blew. Attrition is part of the game, and that's why you build redundancy on the back. Are OD and Morty better options now than Wacha and Porcello were last year? I confess that I do not know. Obviously, the key is to keep your soldiers on the field, and have a redundancy of backups when you can't. It's rough to recruit particularly good veterans for slots that may not be available, because better veterans get MLB contracts, so you have to carry them in the bullpen if a slot doesn't open. I think a key is also building redundancy through the up-and-comers, and lacking a AAA team, it was a really shit year to be a guy on the bubble. Hopefully, if there is AAA ball this year, in addition to veterans with big league and minor league contracts, they could call on Kilome, Szapucki, Jurado (already on the 40), and/or Harol Gonzalez in addition to guys passing through, and those guys won't be coming in cold.
