In 2018, the NFL earned $8,100,000,000 (8.1 Billion). They cant hire 100 full time refs @ $100K/yr (10 Million)?
Each week they could meet in NY Tues-Thurs to go over plays together, do some drills, get rated, educational stuff.
This is a no-brainer to me vs a high school science teacher and a foot locker manager looking at each other wondering what to call or not.
