I think a lot relies on Sale coming back to form. If he still pitches like 2021, they're in trouble.
If all breaks right:
Sale is dominant ace (2.50 ERA and 200 innings)
Eovaldi is top #2 in the game (3.75 ERA and 180 innings)
Hill is solid for a #3 (3.75 ERA and 150 innings)
Pivetta is good enough for a #4 (4.50 ERA and 160 innings)
Whitlock is the #5 (4.00 ERA and 150 innings)
Wacha is the #6.
I can see it working out. I can also see Chris Sale not pitching to pre surgery levels, Eovaldi getting injured, Hill missing half of the season and Whitlock's transition not working.
