He's a high school sports fan. Kind of like me. I watch the super bowl, and the National Championship college game, and, if UCF is having a really good year, I may attend a home game as my wife is an alum. But aside from that, I watch High School sports, especially football. I guess it's because it used to reflect the game at its purest, where the great majority of the participants will end their careers when they graduate.
Unfortunately, it has lost much of its purity over the past 25 seasons.
