Sorry for the missing details. This was 3-person. I was not on the game heard this second hand from the officials on the game. They explained that C was concentrating on ball since he had the last shot. Which he did count and was correct in counting based on the horn.

Even though the Trail and Lead both had knowledge that the clock didn't start they didn't have a count, so they went to overtime and the team that hit that shot won in the overtime.

They did say that had this shot won the game they probably would have gotten together and probably waved the shot off. Not sure how they were going to pull that off if it happened but that's what they said they were going to do.

I think like some have said the best way to handle this situation would have been to blow this dead as soon as any of the officials realized the clock didn't start.

As another contributing factor, they were having problems with the clock operator. He hadn't wanted to reset the clock at one point even though the officials had knowledge of what the time should have been. Plus A was the home team and this ended up being a little bit of a homer clock operator problem.
