It's interesting looking at the two sites referenced above. They demonstrate that sometimes arguments depend on which site someone is looking at. The All Time Database site indicates LSU could claim 6 NCs and Auburn 4 while the National Football Warehouse showsa the more usual...... LSU with one and Auburn with one.
The NCAA site isn't just recognised championships, but the results of all polls, even minor ones. So you have to know which polls were the majors at the time.
Why stop at 3? If we count like Alabama does, it's 6! 1935 - Record: 9-2 Williamson System 1936 - Record: 9-1-1 Williamson System 1962 - Record: 9-1-1 Berryman

But according to these 2 sites, it's not Bama that is stating that we have all these National Championships. It is there in black and white. Some may be from a long time ago, but hey wasn't 1957 a long time ago?
