I think it's more that GM's are lowballing him.
They know every other team is lowballing us, so they're not worried.
I think teams are collectively willing to freeze Danny out until Free Agency, where he'll either be strong-armed into trading 2 picks and/or players just to make room on the roster for our 3 picks (assuming we renounce Lee), or more likely, he'll be forced to renounce 2 of Zeller, Turner, and Sully putting them in FA for everyone else (other option being forced give away 2 of Young, Rozier, Hunter, Mickey, Jerebko and/or Zeller for a 2nd rounders).
That's also assuming we use NONE of our cap space on FAs, or else that's another roster spot we have to make room for.
I guess another option is draft a guy in the first round who wants to play overseas, but you'd need a perfect storm scenario to have him be the BPA.
Trading quantity for quality is one hell of a lot harder than the other way around.
