Hell no. If you want to empty your entire farm, it has to be for a star player under contract for several years.
Among the players you mentioned, I think only Webb is valuable and not overpaid.
Just checked Vladdy's stat since May 1 and it's amazing lol
.218/.316/.278
69 wRC+
-0.2 fWAR.
This guy needs to step up ASAP, otherwise he shouldn't be in the lineup.
