You'd think so, but you have no idea just how much you miss by watching TV. At a football or soccer game, you can follow all 22 players at once, not just the half dozen around the ball. And a baseball game in the summer is as much a warm day spent outside with friends as it is a sporting event. Also you get to see more of the game, since you see how the fielders are positioning themselves and how the base runners are positioned to possibly steal a base, whereas TV just focuses on the batter and pitcher.
Having been to football and baseball games, I do have an idea of just how much I miss. I prefer watching on tv (at least for football, baseball is more fun in person because I find it boring as hell but at least in person I'm there with friends). Obviously this is just personal opinion, but I think there are probably a lot of people who don't care about what everyone is doing and therefore the TV views are more than adequate.
