Think rehabbing veterans will have first dibs on rotation spots until the trade deadline.
Ideally guys like Civale, Quintana, and Cortes (I think Ashby/Hall will be in relief roles once ready) will get healthy and show enough between now and then that they can be dealt for some kind of whatever at the deadline.
After that Peralta, Woodruff (don't think he'll be dealt either way) and some combo of Misio, Henderson, Patrick, Priester, and Rodriguez becomes the rotation for the last couple months.
