I'd want Miller over Chapman and am less hesitant to give up prospects for longer control. In a vacuum, Chapman makes perfect sense but being a pitcher all it takes is a tweak. Varitek/Lowe type package for a pitcher that gets inured then becomes a FA might surpass all other "worst trade in team history"candidates. I'm not saying it's likely, just that it should be a consideration. A consideration that is helping convince me that Miller is worth more than twice as much because of the years remaining. If it's too much for Miller I'd cross my fingers with Chapman.
Or go with Jason's smoking hot pipe dream of Julio Teheran.
I don't see the need in the outfield with Heredia so close. Or O'Neill. Etc.
If it takes Walker, Paxton or Diaz to start the package for any of them I just don't know if I'm on board anymore. Maybe Diaz? Anything else in the minors (over a year in the system) I could see parting with. Zunino...maybe for Teheran. I don't like it so it's probably the minimum headliner. Anybody other than those 4 that could headline that level of acquisition?
I can't complain about bringing in 2-3 middling arms for the rotation and pen at much less cost in view of that. When help is needed, some is much better than none. Zunino heading out could hurt for a long time. At least with Varitek we still had Wilson.
