There is more to dougies point than what you are inferring seabee. Not only is LA, per capita, probably the most talent rich state in the country, they also are unique from all other states in that the talent from birth has been brought up in a semi us against the rest of the country type mentality.
LA natives are a different breed. Spend any amount of time there and you see it. But it goes further than that. Not only are they different, they are proud of it and resistant to the way outsiders are. They also translate this pride and resistance to collegiate football. THIS is the reason few players leave LA like they do Florida. It's not that bama and clemson havent tried - they have, but are always much less successful. Remember when Mark Barron, a consensus five star and the top safety in the country (now an NFL player), had his national signing presser on ESPN with his family and picked up a bama hat instead of LSU (he was nola area native)? His own mother got mad and walked off camera. She came back a few minutes later and was yelling LSU, go tigers!" It was as awkward and embarrassing as you could imagine. But that's how deep the blood and ties from natives to LSU run. I honestly believe there is no excuse for LSU to ever not be in the playoff discussion, EVER. They have that much talent in state that wouldnt even consider any other school. No one did les with more than ol Lester miles.
