If you're an NFL referee (Linesman, Back judge etc.) you HAVE to make at least ONE penalty call per game. Otherwise, you are rated poorly. That premise makes the games validity questionable.
Ball spots. 1st downs (forget the ridiculous chain gang markings), ALL PENALITIES and everything else could be done from the air. The idea that this would slow down the game - MORE - is nuts. Fans won't have to worry about "FIXES".
AND - when the NFL goes to an 18 game schedule - play 9 games per team - give the top 2 teams in that round a play-off birth - play 9 more games and the top 2 in that round will be in the play-offs. The NFL geniuses' can figure out the rest. After week 9, give every team a Bye Week - all at once.
