Morton apparently wants to stay in Florida, so unless that changes, I don't think the Jays have a shot. Obviously if he's willing to go to the highest bidder regardless of location, then a one year deal for him would be the ideal fit.
This does seem like the type of market where if the Jays are going to go big on someone, it would be better to do it on a position player (Springer or DJ specifically). Other than Bauer, I'm lukewarm on the free SP's. Almost all of them come with risk and varying degrees of upside, and I don't think there is one besides Bauer I'd go more than 1-2 years on and feel confident about it (mostly due to health, ex. Paxton, Kluber, Archer).
