I mentioned this in the main thread, but this team has a lot of guys in contract years. I agree that there is a chance they trade a few guys for top notch prospects, but those guys are the same ones that they also might want to extend next year. Chapman is only 28, so they might very well consider keeping him.
You missed Nova, who is in a contract year. If he has a couple good starts before the trade deadline he's certainly worth something.
Beltran's age might hurt his stock significantly, even if they pay that contract.
I imagine Miller is gone. I don't see them getting someone of Erod's quality, but he's still worth a haul.
