Such an interesting thought experiment, guys, thanks!
Completely agree that it is tough to judge what sort of return Freddy would receive, given the 1 year of control remaining. That said, the Mets and Stearns paying X or X+ to get him makes easy sense as they likely could feel pretty confident about extending him.
For anyone else, for a single season of control, I struggle with any offers which seem more that what the Crew got for Corbin Burnes; 2 AAA players with some questions. A recent 1st round draft pick as only a part of a deal seems steep to me. As a comparison of equivalence, I would not want to deal Fischer AND DL Hall AND a high level minor leaguer with a solid tool (Brock Wilken??) for a single year of a pitcher such as Carlos Rodon, if Rodon was making $8MM next year. Rodon finished roughly where Freddy did in the Cy last year, and has some rough other comparisons.
Would I for a single guaranteed year of a pitcher at the Skubal or Skenes level? Yes, so I guess that is my line of comparison.
Maybe I'm too high on Fischer. Just unsure a single season of control is enough to deal someone who has long term upside.
Of course you only need to find 1 team willing to make a grandfather offer.
