no one says 'lets not go to the game, it's on tv"
Bzzt! Wrong! Maybe not many folks do, but I sure do. When presented with an opportunity to go I always decline and say that I would rather see it on TV. (Sometimes this has even been with free tickets). At home, there is no a-hole standing up in front of me the whole game. At home, no jackass behind me spills their beer on me. At home, the noise level is very low. At home, I can see the play and can see it from multiple angles with amazing replays. At home, the beer doesn't cost $10. At home, the bathroom is clean and safe and doesn't consist of a long metal trough. At home, I am unlikely to get attacked by some crazy drunk asshole and my car is unlikely to get vandalized. At home, the parking doesn't cost $25. Yeah, I've BEEN to pro football games twice. Never again.
