The reason the NFL has changed officiating and rules to promote offense is because they are after the lowest common denominator of fan that doesn’t really care about the sport as long as it is exciting. To them, exciting = scoring. The NFL is the most popular US pro sport by miles and miles. Along with college football it is the darling of the media and supports whole industries apart from the actual game. It only got more popular after defense went out the window and fruity celebration dancing and chest pounding became routine. Looking around at the culture, it would be shocking if NFL wasn’t the most popular by miles.

The NFL is no doubt king with college football coming in second. I wouldn’t say defense has been completely eliminated from football. If you go to places like Pittsburgh, defense still rules. Defense wins championships.
