I agree with the too many commercials. It may well be a lot more interesting to be at a stadium, but I've never been to a pro football game, so I have no idea.
I will add this for perspective: Some years back some years back some sports channel on my cable service decided to play the famous (infamous?) Oilers at the Buffalo Bills game January 3, 1993. For those of you not already familiar with this game, at half time the Oilers led 28-3. At the beginning of the third quarter Houston promptly made another touchdown. 35-3. Sensible Buffalo fans started leaving the stadium. Then Buffalo started making good plays. Started scoring. Fans returned. Buffalo made it a tie game at the end of the 4th quarter, won by a field goal in overtime.
Okay, so now you know the bare facts.
But watching that game in more or less real playing time, no commercial time-outs, no endless replays, it was simply the most exciting game I've ever seen. And that was even knowing exactly how it would turn out.
Anyway, I have a team I follow (they just won a Really Big Game) but I didn't watch the game at all. I couldn't, because I don't own a regular TV and I refuse to pay for any of the services that might have allowed me to watch. All season I just waited a half hour or so after the end of a game because highlights were always put up on line, and for me, they are good enough. Although I think if I ever had the chance to watch this particular game in real playing time, I would.
As for actually watching the game, you could consider finding a local radio station that carries the game you're watching, and use that for sound instead of the TV version of the sound.
