Yeah. We've had some disasters where known shitbags bombed, but there weren't really any warning signs that Storen was about to completely implode. Relievers.

Probably one or the other. Apparently they're listening, but not motivated on both.
I'm assuming any deal would require Sanchez + the best 3-4 prospects in the system. But even that might not be enough. I think they'd hold out for an elite young bat (Benintendi or Mazara).
