I would be on board to trade Ryan while his value is high. Otherwise, if trying to compete this year, I would try to trade SWR or Ober for a couple of bullpen arms...say to Colorado for Vodnik and Mejia as an example.
If rebuilding, then I trade Jeffers; if not, then I trade or try to stash Jackson and not worry about getting anything for Jeffers if he can't be extended.
Larnach and/or Wallner need to be traded, no matter what. It seems Wallner would have a better return. Trading both would be good...clear some room for Jenkins and EmRod. Outman needs to be DFAd.
It would be worth taking a flyer on Kopech, whether trying to compete or not. Potential for a high reward.
