I think it is debatable whether Mejia or Brinson is a better prospect. IMO Brinson has a greater range of possible outcomes than Mejia. Between the two, I think Brinson has the best chance to be a "bust", but also has a crazy high All Star type ceiling for us to dream on. I think Mejia is very good, and I would bet on him to become a very solid major league player. If he remains at catcher he will offer a ton of offensive value relative to the position. Even with an elite throwing arm, there is still a chance Mejia doesn't stick at catcher due to some reported defensive deficiencies. A move to third base would obviously be a blow to his perceived overall value. I would guess that if Brewers acquired him they would believe in his ability to stick at catcher, but the flip side of that assertion is it may signal that the Indians didn't believe in him becoming their future backstop.
