The nfl is a $20 billion / year business.
There is no excuse for this type of incompetence.
Pay the officials $500,000/yr, and make them full time. Then fire the 10% poorest grading officials each year. Give the 10% best grading officials a $100000 bonus. This would cost maybev%75 million per year. Less than 0.4. % of nfl revenues.
