Shortening the regular season is the answer. Too many games, too many teams in the playoffs, means that no game has any impact vs an NFL game.
what is fascinating to me as a european living in the US is that NFL is absolute garbage of a sport and it is insane that other sports are not more popular. NFL games are 3 hours of which 2 hours and 50 minutes not a damn fucking thing is happening. the TV broadcast people make more money than all but handful of players on each team (understandably so, they have to entertain you for 2 hours and 50 minutes of nothingness), there is just commercial after commercial… like absolute madness the sport is actually popular to watch. I thought maybe fantasy and gambling are main reasons but you can do both without watching the games
