I think you need to reverse your filters on available pitchers to see who we are targeting. We are not going after the guy having his best season, paying appropriate value for him, to hope he continues it here.
We are going after the guys who have shown to be capable/good guys in their careers who have had a rough 3+ months, that we can acquire for a song, and hope they return to their normal.
I would be FAR more shocked if we trade for Robbie Ray than I would we do something a little wacky and trade for Jose Quintana and his sprained elbow or something.
