This is the question for me. If I can oversimplify in terms of total contract value:
175+: Cody/Boras would likely accept, there doesn't appear to be any team particularly interested at this level
130-175: Unclear if Cody/Boras would accept, they may prefer short term/opt-outs over this. Unclear how many teams interested at this level, probably a few
90-130: Cody/Boras may eventually accept on a short term/opt-out deal, likely a number of teams interested at this level
Obviously there are shades of gray because you can have a larger guarantee that also has opt-outs, but I think that illustrates the tension. No one wants to give Cody/Boras the top line number they want(or maybe close to it), and there's a lot of haggling on what they actually will accept once they start dipping below that line, since Cody/Boras may want to go well under it for a short term deal to be able to get the big top line number after another year.
One thing that does work in the Cubs favor is they have maximum information on Cody, and Cody clearly loves playing in Chicago, so even in a shorter deal where we go from barely any aggressive suitors to many, they should still be in good position if they choose to do so.
