Not only that, but Stripling is a FA after this season and Ryu is a question mark depending on how hurt he is, so the Jays will need to add a SP for 2023 at the minimum, with upgrading 2022 also a priority depending on the health/effectiveness of the current 5. That's why I could see them being in on Montas. The AAA SP depth, and SP depth in the system in general, is lacking. Tiedmann is only 19 so probably not the best idea to pencil him in any time soon, and Pearson is likely a RP at this point.
It might require too much prospect capital to pull these off, but trading for Montas and Happ would be the ideal trade deadline.
