Like it only happens in Texas HS Football? Hey, I got a bridge in New York, clear title, real cheap. Give me a call.
In my misspent youth back up in Wisconsin, one of the schools in our district was Kohler High School. Yeah, that Kohler. Like the toilets. Anyway, Kohler was (and may still be) a "company town." When you bought your house in Kohler, you didn't buy the land, you got a 99 year lease on the land from the Kohler Company.
Anyway, being it the 70s and high-paying union jobs were always well-regarded, it was amazing how many good football and basketball athletes ended up with their daddies working at Kohler and moving to the Kohler School District.
Now, a few years after I moved to Texas, I'm at some sporting event and somebody mentioned that they had relatives working for Kohler in Brownwood, Texas. Some how, my feeble memory is that there was some famous football coach there. Now I found out how he got his talent!
