The point wasn't which was better, but that Toronto added that entire rotation in the past year (plus Walker) -- when they weren't "all-in", either. Pearson emerged from the minors, but looks like he could be a future ace. The others are at least stable... while Boston has Perez. Hopefully, Pivetta will continue to establish himself, but what we get out of the rest is 50-50 at best.
Bauer's not the answer, and the next best thing -- Odorizzi -- is coming off injury... just like Kluber, Richards, Taillon, etc, etc. Teams can never have enough pitching question marks. Maybe this twist on the old adage is better posed as an interrogative: Can we ever have enough pitching question marks? Do we really need more pitching question marks? Can we stop with the pitching question marks?
