Well I guess I look at it as Santana would likely be dealt for pitching. For argument's sake, let's say it is for Danny Salazar. So the Brewers are trading Santana, Brinson, Ortiz and Diaz for Yelich and Salazar. At this point, and given the age and contract status of the players involved, I think the Brewers would be getting the two best players for the next 4-5 years in the deal. Yelich is better than Brinson and Santana. Salazar is probably Ortiz's ceiling as well. Ortiz is the SP prospect I would most like to deal and while losing Diaz would be tough, you have Dubon and then Hiura to potentially fill that void. Not to mention the (small) possibility of a Villar turnaround. I think the Brewers make this type of deal if this is what it costs.
