Referees Rule by Signals
American football, regular football, basketball, volleyball, hockey, rugby or any other sport is full of gestures. Not only do they players and coaches sign to each other or their adversaries, but the referee relies almost entirely on gestures to communicate the calls he makes. Only in some cases does he talk to provide additional information.
Which sport and what signal?
Perhaps the sports unions of the world should start thinking about hiring deaf referees? They may have an easier time ignoring player abuse as well.
