yeah I feel like on a per inning basis, the power ranking of the staff is Palencia/Zeferjahn, then like 6 guys who can all go multiple innings (Gausman, Holmes, Civale, Boyd, Imanaga, Peterson), a couple relievers out of the circle of trust (Webb, Rolison), and then emergency pitchers (Rea, Assad). Thinking about it like that, and considering how the Padres are relatively split neutral (98 wRC v LHP, 104 wRC v RHP) and, per FG, have three positions in a platoon (Harris, Sheets, Salas against RHP, Campusano, Hayes, Taylor against LHP)....what's stopping the Cubs from trying to get 3-4 innings out of two of those six guys, one LHP and one RHP every game, then then finishing up with Palencia/Zef/Rolison against LHHs?
If it goes well, you'd eventually have traditional starters going on short rest. But none of them would be going long, and no one has really earned a third trip through the lineup. Boyd/Holmes, Gausman/Peterson, Shota/Civale.
