Blowing up the team doesn't fix that.
Move on from Dusty and most, if not all, of the coaching staff. Replace Werth. Find a quality backup for Zimmerman (and maybe you have that by moving Murphy to first and playing Difo). Find a good pitcher (not an ace, but a solid number 3). Try and trade Wieters.
Isn’t Eaton going to replace Werth?
