I was shocked that the Nats even wanted him back. But considering the tightwad ways of the Lerners, an oft-injured Shawn Hill is as good as the next dumpster dive reclamation project.
After you calm down maybe you can look at the big picture and connect the dots with the Zim negotiations.
I refer you to Tomterp. I think you and him could have some interesting discussions about the worth of Shawn Hill. 
You might be shocked to find that all of life and baseball aren't found in the little connect the dot book they provide for you at the nursing home.
I see DC's point a bit, the Lerners do have a disconcerting habit of playing hardball in every facet of running their business (except where it counts, on the field

). Unfortunately for them, once they gain the the reputation of being hard-assed pricks to deal with, it's going to be one more strike against us in attracting quality players, coaches, scouts, whatever. Not insurmountable, even Steinbrenner could hire people if he paid them enough, but not a plus for the organization.
On the matter of Hill, it seems NOTLD needs some affirmation

. Yes, for $500k, even $750k, Hill is a talent worth taking the minor risk for. It's clear he's not being counted on, so anything he can give us is a plus.
