I'm more than fine trading DHam, yesterday or last week. I'm sure some team does want him. He'd be snapped up in a minute, if DFA'd.
The return is going to be a single A player or AAAA type nobody, IMO. Sure, let's trade for a nobody who might have a sliver of faraway hope. I'm not against that idea, but I'm also not going to kid myself that trading him is going to make a difference- now or 5 years from now.
Trading Chapman, Gio, Buehler, Wilson, Refsnyder and even Bregman, if it looks like we can't extend him, WILL bring back value. DHam, Grissom, Eaton, Wong, and a few others- likely not.
Story and Yoshida might bring something back, if we pay 60-80% of their contracts or add prospects to the deal.
