I played against Permian when I lived for a year in Ft. Stockton, TX. That was right before the book came out and at the highlight of their dominance. Yeah, they killed us.
First of all, their colors are black and white, not blue. Instant turn off for me. That was Hollywood, let's pretty it up stuff.
Okay, the single most intimidating thing about playing them is the chant their fans have. Not making this up, they get 20,000 fans to their HS games and before the kickoff they are all stomping and chanting Mojo, Mojo, Mojo over and over.It will scares a HS kid to death. When the movie did not portray that aspect of the story I was disappointed in it. That was as intimidating as any of their players or play on the field.
I'd have loved to play there with that kind of home town pride and advantage. What an opportunity! Nothing but respect for the real story and team, the Hollywood versions of it leave me flat.
