I posted a few years ago that the NFL was diluting its brand with all of the extra days. Scarcity creates a build up of anticipation. The NFL was talking about going to 18 games - used to love the idea, now think they should go the other way. Go to 14 games - and with all of the new players in the content wars, sell rights by teams or by divisions, and use all mediums. Apple is getting into the game, that means Google and Samsung are already working on their versions since all these company's copy themselves like its is their calling. Netflix, Hulu, traditional cable, premium cable, and the old horse who used to be the only guy at the table - the broadcast networks. Revenue would skyrocket beyond belief.
Honestly love the idea... Otherwise expand the season, not in games but lengthen the timeline. Instead of 16 games in 17 weeks make it 16 games over 20 weeks. Plus they could spin it as helping players physical health,and it'd increase the scarcity factor and would reverse this downward trend.
