From a Bama premium board, within a thread about defending their 12 titles:
<font size="2">Now, the "questionable" ones would be 1930, 1934 and 1941. In 1930, we won the Southern Conference championship with a 10-0 record. We gave up only 13 points all year and beat previously unbeaten Washington State in the Rose Bowl. Notre Dame also went 10-0 this year. At worst, both schools can claim a split national championship.
In 1934, Alabama again went 10-0, won the SEC championship and beat Stanford in the Rose Bowl. Minnesota went 8-0 and won the Big Ten. They did not play in a bowl game. At worst, again, both schools can claim a split national championship.
Add the 2 split national championships to the other 9, well, that's 11. The only one I can't defend is the 1941 championship claim. We went 9-2 with losses to Mississippi State and Vanderbilt. Minnesota again went 8-0, won the Big Ten and were named national champions by the AP. This title clearly belongs to them. However, considering the screwing we took in 1966 when Notre Dame and Michigan State tied yet both still finished ahead of undefeated and two-time defending national champion Alabama in the polls, I don't mind claiming one that might be a bit questionable as compensation.</font>
