When I was playing in high school I cared. Maybe the next two years after I graduated I still cared (about 75% less though) because my brother was still playing. But in the six or so years since? I can't even remember going to a game (it's possible I went to one homecoming event but I highly doubt it); hell, I don't think I've been to my old high school since my brother's graduation, and I have no reason to go.
