[just another ref]

On the subject of cognizance, back in the old days I was not registered and just called locally, jr. high and below. You know, the games where everybody knows you and can use your first name when they insult you. I was actually advised by coaches and "real" officials that knowledge like this was a bad thing.
"Put it out of your mind." I think this is largely good advice, but many times is impossible to follow, especially when it involves the star player being in foul trouble. You hear it shouted from the rafters: "Take it to him! He's got four!"
