I agree with you, but I don't think it's out of the question, nor should it be summarily dismissed in the trade forum.
Why wouldn't the Angels consider trading Neto, or the A's consider trading Wilson for The Miz, or a collection of prospects including Made or Pratt? Why wouldn't the Brewers consider acquiring those [nearly] proven MLB infielders with team control?
If the Brewers are worried about their gloves at SS, just put them at third. In this league, their bats are good enough for 3rd base. Heck, Bregman has made a lot of money being a "lighter" hitter at 3rd rather than a good hitting, below-average defensive shortstop.
