Football mechanic in basketball game

[JRutledge]

I either point or use a thumbs up to let my partner know that I am ready, which usually means I have counted players or we do not have subs to come in. It is not a "prescribed" mechanic, but there are a lot of things we do that are not prescribed. Now your partner's exact signal might have looked a little goofy on the basketball court, but I do not see why this would be a big deal to anyone other than it looked goofy. Are you saying that we should not give a single to each other just because it is not in a book somewhere?
