I had a game this year where the clock stopped on 00 twice (older small gym old clock). In both situations we were shooting free throws(end of 2nd quarter/end of third quarter).
The first time I went to table to check the clock it read 00.7 second time 00.2.
My partner and I then had the information on what type of last second shot would be allowed. Told both coaches how much time was left.
We had pregamed this because of the old style clock.
