I'll say this, 2019 had the best on field primetime games that I've ever seen!
Over the years, the rules have made it easier for offenses. That may give the allusion of a better game, but isn't necessarily the case.
I have a great appreciation these days for watching HoF QB match-ups(Rodgers, Wilson, Brady, Brees). I get just as much joy in watching the young guns (Jackson, Mahomes, Allen, Murray...).
I do miss watching consistently good/great RBs, who can run between the tackles and truly dominant defenses. Dalvin Cook, Derrick Henry are the only guys who give me that. Who's the dominant defense these days? There really hasn't been one since the Legion of Boom.
