Coaching we've had two situations like this already this season, both handled differently. (btw, NJCAA-W game)
First game, official scorebook wasn't even at the table until 5 minutes before tip-off. Officials gave them (the home team) an Administrative technical foul for not having a book. Our best FT shooter wasn't starting that day, but was able to shoot the 2, and then go back to the bench. However, they still had a jump ball to start the game. Wasn't sure if you set the arrow or jump in NCAA rules, but it wasn't a big deal since we got to start the game up 2-0
Second game happened this weekend. The home team put 7 players in their book, and ended up playing 9. When we saw they were using a new player, we notified the officials and they said it was no big deal. Our HC got so upset he started going off. Luckily the officials did not T him up for his demonstration.
(BTW, these guys also waved off 5 three pointers because the 20'9" line is the "College" line and the 19'9" is the "High School" line.)
