There was similar rhetoric this time last year about how they wouldn't be doing that kind of stuff, but attrition happened and they ended up doing it. I don't think you plan for bullpen days, but know that in a pinch you can do it over signing an abundance of veteran pitchers. Between Skubal, Webb, Jobe, Olson, Mize, Manning, Hurter, Madden, Montero, and Maeda, chances are you have five starters somewhere in there.
