After Bauer, I'm not sure there is a right answer as far as which SP to sign. There are a lot of pitchers coming off down years or injury, and a pitcher like Tanaka whose arm will always be considered a risk. Sugano could easily be the 2nd best SP on the market despite the uncertainty of how he will perform in the Majors. I'm sure there will be at least one SP out of the group of risks (Odorizzi, Kluber, Paxton, Quintana, Tanaka, Archer, etc) that will end up having a great season in 2021, but it's really a coin flip, and hard to know whether those pitchers would even want to sign with the Jays if their intention is to increase their value for a future payday. Ray falls under that same group, but he just happened to pitch here for a month so the Jays got the advantage of building a relationship with him.
If Passan is correct and the Jays could steal Springer from the Mets, then a Springer/Kim/Sugano off season would be pretty good, IMO. Even if Springer signs with the Mets, the Jays could spread the $25m that they would have paid Springer into multiple holes (ex. JBJ and another SP). CF might be the hardest position to fill if Springer and JBJ sign elsewhere, but other than that, the Jays are in a good spot.
