yes, i think the move for Skubal makes as much sense for the Brewers as anyone. A third true "1" probably stacks us up quite well against the Dodgers in the postseason.
That said, nobody on your list is considered a top 100 prospect, and that seems unlikely. The Dodgers and Brewers both have a healthy number of top 100 guys, and I expect any deal to require 1-2 of those types. A Lara, Williams, Fischer, Payne, Letson.. maybe even a Pena.
The argument against by the FO is that the Brewers is still rising in talent and youth, so why sacrifice the future? But you'd certainly like to see this window of Miz/Contreras/Harrison/Turang/Chourio be used well.
