I can only offer some tangential information. I worked with a guy whose dad was a small town high school football coach (although not in Texas) and he said that if the team lost Friday night, he didn’t want to go out in public Saturday because at the very least he was going to get the stink eye from everyone in town. After a particularly bad season or two, they would pack up and move on to the next town that was looking for a coach. The guy said he found the characters from the TV show based on the Friday Night Lights feature to be very sympathetic and the plot lines rang pretty true as far as his own experience went. I originally wanted to say it was more of a small town thing than a Texas thing, that maybe people had such an investment in the town’s high school football because so many of them stayed in the town after high school rather than moving away or going off to college, so high school football was all they knew. I think you’re right, though; it is far more prevalent in Texas than anywhere else. I knew a girl that grew up in the suburbs of Dallas and high school football was as big there as it was anywhere else. It was a rather affluent suburb with lots of people that had lived elsewhere, but had come specifically to this town to put their kids in this high school that had such a good football team.
