I went on a rampage and emailed Schopp at WGR on this subject- almost 20 years ago!
Among other ideas...
1) Full time wages- no more Part Time Used Car Salesmen.
2) Hires only, from ex Division 1A Football Players who didn’t get drafted and have a superb knowledge of the existing rules.
3) Must be in superb physical shape, with 20-20 vision, and a Wonderlic > 27. Fat, slow, blind and stupid are out- immediately!
As in the entire existing NFL cadre needs to be sacked immediately!
4) Refs, Line Judges etc. are Graded every week. Any highly stupid call or NON call of the blatantly obvious? Out you go! Any flagrant miss of spotting the ball? Out you go!
5) Digital Electronic marking of the entire field and End Zone to assist any Out of Bounds calls!
