when i lived in louisiana, i played pop warner down there. they literally had us catch passes, practice, etc, and then had a draft. ( like a real draft, that parents and fans, yes FANS, would attend).
the amount of teaching in football, resources, seriousness, etc, all develop the talent down there more.
when i played football in louisiana, and then hs ball in va, i had to move to michigan when my dad retired during my sophmore year. so i spent 3 years in hs in michigan. the practices were way harder down south. you could even see a stark difference in football in north carolina... we would go down there for bowl games and there would be like 10,000 maybe even more people attending...
also keep in mind, the sec has two great great teams, and then the other team are usually even with others. plus the sec doesnt play by the same rules...
