There's no sports in your violence

I am frustrated that the news covers these jerks attacking each other. My idea for contract writers: "Throw a punch, throw your contract." If they don't want the violence, financially fine each player a substantial amount, not just a "you can't play today" penalty. I understand that the days are then "unpaid", but limit the violence by harshly punishing the offenders. Adopt the "throw a punch, throw the contract" concept, wherein simply an attack nuls and voids any financial obligation the team and franchise has to that player.
