I saw someone post this on another forum. The Burnes trade last year is a good baseline for what Cease or King might cost.
Baltimore gave up Joey Ortiz (#42 overall prospect FV 50), DL Hall (former top SP prospect turned reliever), and a 2024 Competitive Balance Round A pick (No. 34 overall).
Now, that package was considered a bit of an overpay by the Orioles at the time and Cease is certainly not considered quite as good of a pitcher as Burnes was a year ago. And obviously the Pads have different needs than the Brewers did a year ago, but a similar package from us might look like this:
Nacho (Top 100 overall prospect), Waldrep (former top SP prospect whose stock has fallen), and a our 2024 2nd round pick Carter Holton. And this trade would likely be considered a fairly sizeable overpay.
