I'm gonna backpedal a little bit here, but you can redact my statement then and interpret it as "I'm only sick of the NFL because they managed to politicize sport, which, in regards to the average fan, is literally supposed to be an escape from that noise."
I'm not ignorant of the NFL's success, I'm more focusing on an idealistic aspect of sport being eroded within the country's most popular game, which, for me, is the fact that on the field all the players are equal and represent the same team, and they deserve the support of the fans regardless of who they are or where they came from, and that is not conditional support based on the personal views of players off the field, who we forget are human beings with families, opinions, and emotions. (I have views on the handling of recent controversies which, if elaborated on in this thread, would promptly get modded.) It's a non-issue for the NFL probably, as the owners can pretty much do whatever they want and still make more money than god (part of why I'm a Packers fan: no single "owner"), but anecdotally, could be a issue for a long-time fan on either side of the coin.
Then again, I'm a hypocrite as a soccer fan, which is the most notoriously corrupt sport on Earth. (The NCAA is pretty sketchy, too.)
With all that said, Packers 8-8 season, we'll finish ahead of the Lions and Bears. The goal is for Rodgers to stay healthy. Ho hum.
