They are not necessarily all at the game. You could have Grandpa homebound and can't get there. Maybe the weather is bad. Maybe you cheer for the road team and don't want to/can't go to the game. Maybe you graduated 20 years ago and don't have the time to go but can catch the second half when you get home. If it a game for other teams in your conference/region, you very well might watch at least part of it to see how good the other teams are.aren't most pf the people who follow a HS FB team already at the game? do they watch other HS FB games that don't have any impact on their team?
