Texas style football has nothing to do with offensive or defensive philosophies. It has do with culture.
Texas has extensive Spring 7 on 7 football.
Texas doesn't have Lacrosse as a sanctioned sport.
Texas has a 10 week season with possible 6 weeks of playoffs. A team can play up to 16 games in a year.
Texas still employs almost a full month of 2 a-days.
Texas has Spring practice just like colleges.
Texas has HUGE fan support.
Texas has flourishing youth football programs with kids starting as young as 4. This is true even in small towns.
Most Texas kids specialize and there are many sports training facilities in the major cities.
Until New York and New England can match that, there will continue to be a huge gap in talent.
