I think Cora is really good with the pen he's been given. (2018's was pretty good, but it started leaking late in the season. I remember some felt Joe Kelly should not have even made the playoff roster, yet he turned into a hero.)
As for starter health, we did lose Sale for most of 2021, and Houck missed some time, but yes, the rest stayed very healthy.
In 2020 (no Cora), we missed ERod and Sale and 25% of Eovaldi's starts.
In 2019, Sale missed time, Price started just 22 games and Eovaldi just 12. We got 37 starts from Velazquez, Johnson, Cashner, Chacin, Weber, Lakins and 4 others.
