Why you don't do a 5 second count in your head

[CMHCoachNRef]

Hogwash, hogwash, hogwash. If you can't do two things at once, become the damn ballboy. The mechanic is simple. When the player is closely guarded, you begin the count with the proper extension of the arm. Each extension of the arm -- STARTING WITH THE NUMBER ONE -- counts toward the five count. While the "not closely guarded" signal is new to NFHS, the fact that we change arms and stop the count has been a mechanic forever.

Officials who do the first one or two counts "mentally" will NOT get to do high level games. I always looked at the official to see if he was counting. The mechanics manual tells us exactly what to do. Don't make excuses as to why you can't do it. Just practice it until you can watch for things like a travel, a bumping foul, a player control foul, etc. while extending the arm and counting.
