I think that this is who Eaton is. Even still, had Alexei and LaRoche performed to their career averages, we'd be in the middle of this.
In my mind, nothing has changed. If you can improve your team for the next three years (in other words a MiLB player or players ready to start at the MLB level next year), you pull the trigger and trade Samardizja. If you're offered guys that are further away, you extend your middle finger.
The goal has to be to get to the post-season in the short term. Chris Sale is the ideal game 1 SP, and all movement should be made to put yourself in position to run him out there in that situation. Unless of course, you intend to rebuild instantly by trading him, which it appear there is little desire to do.
