I'm fine standing pat with Quintana/Sale if they think they'll have more suitors this off season. There's really no reason not to sell high on guys like Shields, Gonzalez, Robertson etc. I guess they want to be bowled over by every offer.
Looks like Charlie Tilson will be the last interesting element to this season. He makes his debut tomorrow. He'd have been in the majors with STL soon enough, and had a pretty easy time getting on base in the minors. Legit CF defensively, + speed. We'll see about the bat.
I've heard the "more suitors in the offseason argument". I just don't buy it myself. The teams that will be suitors in the offseason are in pennant races this year. So, we are expected to believe that we'll get more for those guys when they can influence one fewer playoff push?
Are we expected to believe that the other GMs were unable to look at the upcoming FA class and see that there was nothing available and they'll therefore be stuck?
But as you mention, even if you want to believe that, you still need to get something for Melky, Robertson, and other peripheral pieces. Some of the returns this week were IMO ridiculous. I find it hard to believe we weren't getting fair market offers. I choose to believe instead that Hahn is deluded and should be put on medication.
