When I was coaching, an opposing coach had written down all of his players' away numbers for a home game. He had a tech for each player with the wrong number in the book (even after being questioned by his scorekeeper!). I had a real good free throw shooter and we started the game ahead 14-0. Ended up winning by 20.
I hope that didn't really happen. If so, the officials blew it. There is only one administrative technical foul no how matter how many violations of having the wrong number in the book, or for any book violations for that matter. NFHS rule 10-1-2 (Pen.)
