I think it was Doug Melvin who said that pitchers are worth more at the deadline and hitters are worth more in the offseason. And when a team acquires pitching, they usually have to give young pitching back; if they don't, they usually have to give up a lot of hitting.
Sure seemed like that this year - when young pitching was given back, it didn't seem like teams had to give up as much as when only position players were going back.
But the Brewers came out of the deadline without giving up Made, Pena, Fischer, Adamczewski, Pratt, Lara, Payne, Burke, Letson, Knoth, the elder Ebel, Hardin, Quero, or Dinges. The future is still bright.
I think Romero is a sneaky good acquisition. Career 51% ground ball rate plays well with this defense, and has saved 12 games over the last 3 seasons.
