I'd agree Brewers probably would've been darn close to saying yes to 7/166 if it was on the table before trade. I'm sure he expects way way more than that though. That seems a very low estimate right now as he's stayed healthy and performed well in a tougher division.
I have a feeling even if general plan for NYM is play it cool for a couple years that the owner will get antsy and make a big offer. I'd put NYY in the less likely group to start based on expecting them to have to pay like 10/500 for Soto, while still having Judge, Stanton, Cole, etc. But if Soto leaves it frees up a lot. Random note, Stanton is down to 3 years left after this year, so its getting close. Could also start to see other teams start pulling the Ohtani deferred route before it gets banned, which would help a team like NYY spend for him and Soto at once
