I agree with this, but those guys will never be hired. If there is a Manager who has a vision or style that conflicts with what the organization wants to do, he'll never make it past the interview. The organization will need to revise its thinking first IMO before a Manager like that is brought in. This is why I think Krall needs to be the first to go. Then whoever replaces him should decide what to do about the Manager and Coaching staff.
Also, understand that major league baseball is not College or High School or even the minor leagues. A Manager's job in the big leagues isn't the same as a Manager at those other levels. Just the fact that the players are unionized means it all needs to be handled differently.
