One of the reasons that high school football is difficult to watch for most people is that the players just kind of suck. You could go to 100 high school football games and not see one kid destined for the pros. Unless you have an investment in the team, like you go to that school or you've got a kid in the game or you're on a list, then you'll probably be disappointed if you're used to watching college or NFL games.
But sometimes you can get lucky and witness a special 16 or 17-year-old kid who is playing on another level and isn't just out there for the cheerleaders.
