I think there's some NFL pass things that allow you to do that, actually, where you can watch everything whenever. A lot of them aren't accessible from Europe sadly, but if you're American there's plenty of options for you.
There's also sports anime lol
That's how I got introduced to American football, watching and reading Eyeshield 21, and it got me interested in seeing the real thing. Sports anime are pretty cool since they present you with a curated narrative with lots of ups and downs, and they're usually a lot harder to predict than traditional shounens, since losing doesn't doom the universe or something. They're genuinely a nice entry point to sports in my opinion, at least if you enjoy anime already.
I just think the sport is really neat.
The ads are pretty overkill even compared to watch I see here in Europe during the soccer world cup, and yeah athletes are paid ridiculous amounts, but at the end of the day it's a lot of fun to watch, at least for me. It's a battle of both wits and raw athleticism between people pushing the limits of what the human body can do. That's super cool, and all the story lines that arise or crumble from the competition are immensely entertaining to follow.
When you get down to it capitalism tarnishes everything anyway, a lot of entertainment media is very much just vehicles to sell even more shit, but they can still be enjoyable in and of themselves.
