Because the NFL is not fixed. If you even thought there was a slight chance that it was, why in the world would you bother watching?
...For entertainment, like the rest of the world? To be connected with a community, society? To watch athletes on display? I'm not questioning the legitimacy of the sport, I'm questioning the legitimacy of the corporation.
You're going to have to provide me with reasoning as to how you see the NFL couldn't be fixed, because I just don't see it.
EVERY sport has a history of rigging. Especially one's with gambling. The NFL basically has the largest entertainment brand in America, followed by legal freedom to do as they please. I mean, any way I seem to cut it in my mind results in the NFL tinkering in its games. This is about money, this isn't about the integrity of a sport. That should be obvious with every single action the NFL and Roger Goodell does.
