Eleven slides, eleven penalties, eleven signals dispersed from several referees, at different locations - how will any of us be able to keep up with the action.

How many different signals are there in Basketball or football?

For football, there are more than 11. (Offside, false start, personal foul, incomplete, catch, touchdown, safety, holding, facemask, out of bounds when catching, roughing, clock run, delay of game, and the down calls are the ones I can think of.)
