This is a bit of a post-mortem.
At the end of 2018, we though we were in pretty good shape, pitching-wise. We had 5 regular starters, without Johnny Cueto and Jeff Samardzija, and they had collectively given us 125 starts during the season.

Madbum 3.26 2.4
Holland 3.57 2.1
Suarez 4.49 0.5
Stratton 5.09 - 0.8
DRod 2.81 2.5
That's 6.7 war out of our 5 starters. For the record, we got 9 or more starts out of Ty Blach, Jeff Samardzija and Johnny Cueto, before they became injured. What's more, we seemed to be getting out relief staff to work the way there were intended to.
