Football can easily solve the over acting if they took lessons from hockey. First, they get fined for faking. The second is that you have goons to police the field which will intimidate anyone being reckless. You would think twice about biting someone or putting cleats into another person if you had to square off against an enforcer who pummels you until you concede defeat by putting a knee to the ground. The thied is any injury that stops time forces the player to go to the dressing room to be assessed by a doctor. He then decides if the player returns, not the player or coach himself. You won't see nearly as many injuries cured by a magic spray. The fourth is making everyone line up and look each other in the eye, shake hands and congratulate the winner.
