Great summary.
I've never been one to support a 6 man rotation, but with the depth of starters we have, this may be the exception. The other idea would be to selectively choose one to move to the pen and give it some quality mid to high leverage innings. We will likely need pen help, too.
If everyone stays healthy (little chance) we may have Crawford and Sandoval to take some bulk but meaningful pen innings, and I struggle to imagine using Early or Tolle in pen roles, but if the other 5 are doing very well as starters, that may be what happens. Perhaps, we end up moving Oviedo or Bello to pen roles, but again, this is going on the longshot assumption everyone stays healthy.
It's hard not to view our top 9 SP'ers as one of the best and deepest 9 this team has ever seen.
Crochet, Sanchez, Gray, Bello, Oviedo
Crawford, Sandoval
Early, Tolle
