Sorry, but you are the one who is incorrect.. You don't know enough about the game and you've shown that through out this thread. That is the problem. And you don't know SQUAT about human nature and human psychology. For you to think that a whole sale change at all your coaching positions WON'T result in some conflicts shows you to have no real life experience. You are overlooking all the changes among the positional coaches. Those are the coaches that work directly with the players. You can't sit there and tell me that they doe EVERYTHING exactly the same as the previous coaches. I can guarantee you, just by human nature, its impossible.
So, while the GOAL is to be winning and acting as one, how the message is presented and received takes getting used to. Particularly when there is a wholesale change. Also, when positional coaches do things differently the players may not always like it. And if you think that change comes easy, then I know, for a fact, you don't know what you are talking about. I spent 10 years in industry working with people to change their ways of thinking and their ways of doing things. Unless they buy into it, it WILL FAIL. If the positional coaches can't sell their ways to the players, your team won't function.
