I do not think a lot of fans understand refs are human and will at some point let their human emotions surface.
What I mean is this: think of the little league coach who has a parent constantly bitching about their kid. Finally the coach makes a move and plays that kid. Question is, did the coach put the player in due to his/her skill or just to shut the parent up?
Coaches make moves like this.
As a coach, a ref, you start to question your decision when it is constantly thrown in your ear. Your brain starts to second guess you.
True story: I had a kid pitching who went onto D-1. This one game she was getting very upset because she felt the ump was not calling the game correct. No matter what I tried, no matter all the mental training we worked on, she was focused on him.
I went up to the ump and asked him where she was missing the strike zone at; explained to him that she was very good and my catcher lies to me if I ask her what is going on, so tell me where she is missing at and so I can make an adjustment. Umps are not all bad but all have egos.
I went to the mound and spent a few minutes talking to her and what I said was this: "watch me (I was going thru pitching motions) and act like you are making an adjustment." She tried a few non throwing motions not doing one thing different. The ump starting calling her pitches strikes.
In a clinic once, a mental instructor told us to get in the umps head. He said to the them " all I hear is "ball, ball, ball" so help me. Get in their head and at some point their brain starts to second guess their decisions.
It does work. I know from first hand experience.
So, when I watch the Alabama coach constantly in the refs ear, the start of the second half was crap for us. Look back and see if the last few minutes of the 1st half if Oats wasn't all over the refs.
