Agree on Hader being more valuable than Brinson. I do think Hader's role will be in the bullpen. I don't want to give up Hader, but you have to give to get and I think it'll take Hader included to get Quintana, and I think 3.5 years of Quintana is worth giving up Hader for. I wouldn't include Hader, or Woodruff for that matter, in any trade for Gray. Considering we have a logjam of talented OF prospects, the organization can afford to give up Brinson, even if he does becomes a reliable MLB starter, which I think is reasonably doubtful. Of the position players in the system, the only players I wouldn't want to trade are Mauricio Dubon and Keston Hiura
