This isn't exactly "NFL", but it is high school
football in Texas: $60,000,000.00 for a &^$$&-in
high school football field in the Collin County town right next door to me, Allen, TX. http://www.dallasnews.com/sports/high-schools/football-news/headlines/20120824-photos-where-eagles-dare-....-allen-unveils-massive-60-million-stadium.ece
BTW: the UT-Austin coach, Mac Brown, is the highest-paid "public servant" in the Republic of Texas: $5 MM/year + "extras".
As a native of Pittsburgh, a town which has produced a few decent HS players that went on to "bigger things": Unitas, Lujack, Namath, Blanda, Kelly, Montana, Marino (just to name a few from just one position that come readily to mind), I really have to laugh at my adopted home state of Texas.
