The last Management of the royals really did a bad job, especially with developing pitchers.
Vinnie is really good and if witt and melendez can improve it could be a solid offense, it least the top and middle of the lineup, but pitching really has been bad.
There is a bit of hope though, they are trying to modernize the system and reportedly have sent some pitchers to driveline this off-season.
Still overall the rebuild so far hasn't worked all that great.
