Brewers FO has been flipping players for prospects with a high success rate for a while now. I dont think its fair to pick out a micro trend of one set of prospects returned exceeding those of the other.
That said, the org desperately needed depth and they have been building just that with their unique draft approach, international pipeline and flips.
But i think the bigger question is how is the league going to adjust to the brewers strategy, which would dilute it? if so and maybe anyways, the brewers depth is create organizational pressure now, and so at what point do they move off this approach and start thinking about bigger pieces as their depth is pretty well solved.
