That's a potentially decent rotation even without Skubal and Mize, but, of course, they've got to stay healthy. I'm still dreading the eventual Tommy John surgery for Melton and Montero.
I suppose they could still re-sign Mize, but I'm predicting he's gone. (There's also Drew Anderson, who could also potentially start if needed).
There's also a little bit of starting depth in the upper minors as well with Madden, SGL, Jake Miller, Andrew Sears and maybe Joe Miller.
I don't see a huge incentive for Harris to sign a veteran starter this coming offseason, but you never know, maybe they're not sure if Olson will recover his previous level.
The Tigers will probably need to sign some bullpen help. Jansen has a team option for next year, but I doubt they will bring him back. Jansen also might get traded at the deadline.
Closer duties could go back to Vest or maybe even Anderson. Finnegan will be back as well. I'll beat a dead horse, but I still think we need a reliever or two who can miss bats.
