NFL telecasts include a smaller share of game action than in any other major sport -- even MLB.

We've had umps calling games for 100+ years. It was fine the way it was.
Soccer has it the most correct of any of the major sports (and it sucks there too by the way). The VAR official will call down to the referee on the field and tell them to go to a monitor on the sideline and give something another look. Coaches can't appeal. It truly sucks but this is the best idea of all of these silly video reviews.
What is truly hilarious is that even with video review, there still are massive amounts of complaints about referees and calls.
