I think the NFL has more than a ruleset problem and an accountability problem (and it certainly has both of those).
It also has a recruitment and hiring problem.
This ruleset is ridiculously complex and requires of its officials to be able to perceive spatial relationships and physical interactions at extreme speeds and make immediate, correct adjudications.
You know who is good at that? Young, extremely adept video game players of a certain ilk. They should be selecting for those traits when they recruit.
That doesn’t seem to be the current refereeing base in the NFL!
