I'm all for keeping as much of our youth as possible, but the fact is we have bottlenecks at several positions and too many expensive vets that are near impossible to jettison. Eventually someone will go. To maximize return, it will (or should) be someone with a high stock value.
I caught a lot of grief for suggesting we offer Swihart due to the fact that we had Vazquez, and Swihart's highest value is as a catcher, and catcher's are in very high demand in MLB.
I see Moncada and Benintendi making the chance Devers ever wins a FT slot as being very hard to happen, even if we somehow are able to get rid of Sandoval and Shaw fizzles out by the time he's ML ready. That's also assuming Travis and Hernandez never do well enough to win a key role on the team. If Moncada wins an OF slot, then where does Benintendi play? More likely, Moncada will have to play in the IF.
To me, our best package might start with Swihart and Devers, even though Devers' stock might have slipped this season a little bit. To me, those two headliners net us way more than a rental- even a great one. If we add other nice pieces like Owens, Johnson and/or Kopech, the return should be even better.
