Exactly... the most fanatical football nuts I know are the ones watching the game on TV with the different angles and the slow-motions and the replays... the people going to the game are very tribal, they love painting their faces and shouting [CITY NAME] and they do genuinely get very happy when [TEAM] wins but they aren't the ones talking about the 0-technique of the defensive lineman and so on.

Of course, but having been to an F1 race recently, the tracks are so irregularly shaped and long that it's usually impossible to see the whole track (or even more than some small section of track) from the stands. And even the big screens can be sparse.
