Gray and Maeda pitched 288.1 innings at a combined ERA of 3.31 that needs to be replaced. IF Ryan can pitch 25 more innings than last season, Ober 30 more innings and Paddack can pitch 125 innings (I'm hoping he's closer to 150 IP) that covers 180 of them. IF Varland can pitch 100 more innings than last season that covers the lost innings. Headrick may be stretched out for long relief/spot starts, there's been talk about stretching out Duran (we'll see) and there are also arms waiting in AAA & AA (Canterino, SWR, Festa, Raya). There will also be non-roster ST invitees (oh dread).
Another arm would be nice, probably necessary given how common injuries are to pitchers, and may happen, but Falvey and Levine are delivering the pitching pipeline.
