Don't we have a pretty good (and recent) comparison for what a Cease package might look like? Heck, we just traded away a big time SP in Burnes last year at this time - and he too only had one year left before FA. With that said, I don't think Cease is quite to the level of a Burnes....so I think you could make an argument that it could be a slightly lesser package going back to the Pads.
If memory serves me right, at their peak rankings - I think both Hall and Ortiz were back-end Top 100 prospects. In fact, during the '23 season MLB Pipeline had Hall at 97 and Ortiz at 99. So, with that said - there's no way the Brewers are giving up any prospect currently inside any of the Top 50 prospect rankings for one year of Cease - so that should rule out Q, Pratt, Miz (although we know his rankings fluctuate more than most due to his reliver projections) and definitely Made.
I could make the case for a Gasser/Black package going back to SD, but we know Gas is coming back from TJ surgery, and how often do you see guys getting traded from one organization, only to be traded back to that org just a few years later? Seems like the odds are probably low of that happening.
Maybe a Henderson and Boeve package? I wonder though if we'd have to throw in another lottery ticket type piece to that package too? Maybe a Jorge Quintana?
