Here is the closest thing to a contract prediction we have for the SP of interest from back in August:
https://www.mlbtraderumors.com/2023/08/2023-24-mlb-free-agent-power-rankings-august-edition.html
Yamamoto - "easy to envision him receiving offers of eight years...opt-out opportunities"
Montgomery - "Taillon (4/68) and Walker (4/72) feel like more of a floor...ought to be able to command a fifth guaranteed year...nine-figure deal"
Nola - "five or six year deal topping nine figures should still be attainable...$162MM...were it not for the home run concerns"
Giolito - "six-year deal still seems plausible"
Snell - "legitimate Game 1 starter in a postseason series...nine-figure deal of five or more years in length"
Hader - "will take aim at making Diaz’s (5/102) record"
Lorenzen, EdRod and Stroman in the HM section with no real info.
So the play seems to be bring back Morton, then wait to get one of the guys listed above on a 3 year deal, or be the team that jumps at Yamamoto. If that fails be the team who grabs Lorenzen, EdRod or Stroman.
