Why do this? #1 prospect. Nobody.
The question is who of Weimer, Mitchell, and Frelick are you trading. That's going to happen to create a spot on roster for him in OF. Every game that passes with Frelick in the minors, after this road trip, I assume it will be him. Chourio is like the Brewers franchise version to the Bucks with Giannis now in his 2nd season. Obscure. Hits the ground running. Accolade on talent.
Why trade him for a star with a large contract? Like for a second I thought about Julio Rodriguez but basically that's just Chourio 2 seasons earlier.
Ugh, now I suppose being in win now that is who I'd trade him for. I'd send Seattle anyone else they asked for with Yelich and make extending Woodruff or Burnes with the money opened up long term.
