I always had students who asked to be our scorekeeper. I never had one go in blind though, I always taught them what to do and to stop and ask the referee if they needed clarification. They too wore the referees shirt at the table here in MD.I kept the Home book for Boys and Girls basketball for 15 years. I think that most fans would be surprised about how many errors are made every game between the Home/Visiting books and scoreboard. As stated- the actual score is the Home Book.
They key is constant communication and FIXING problems in real time and/or at the next stoppage.
Typically errors are player fouls, possession arrows and time outs. Never in my personal tenure was the score wrong, but we have had instances where the board showed a 3 and the refs had called a 2....which needed clarification and was changed.
An older gentleman who had kept the home and away book for 20+ years for an opposing conference school was maybe the best I've ever worked with. Very business like and serious. The Home Book keeper is considered a Game Official and wears a referee Jersey.
That gentleman resigned when only after reconciling his book after his team suffered a devasting home Overtime loss, did he realize he did not properly account for what he had as a Home basket in the 4th qtr which never made it to the scoreboard.
My wife accidentally closed a door or my writing hand a few years ago- and I was uncomfortable enough to give up the Book. I got move to Ticket Checker- which pays only $10 less but has ZERO stress....and you get a courtside seat to watch the game!
I'm sure those involved feel awful- society in general is much less forgiving about ANYTHING these days. The $ is not worth the aggravation....
One young lady who I had in both Honors Pre-calculus and AP stat as a sophomore asked to be a manager but she was exceptionally bright so I showed her how to do the book/table. It didnt take long before she was like an assistant coach. She would yell over how many fouls each person had, who had possession next JB, etc. By her senior year she was asked to be the home book for other various schools playoff games. On our senior night she went out with the team and we announced that she was going to Morgan State University in Baltimore to study engineering. One of the officials asked her if she was interested in working with the mens staff there and soon after Todd Bozeman called me to ask about her. She was a 3 year member of their scorers table (she graduated in 3 years) and got paid while doing it. She even got to work when MSU made it to the NCAA tournament and played Oklahoma, with Blake Griffin, in the first round.
