In the spirit of Alabama I did some research and decided that I'm retroactively declaring the University of Wisconsin national champions in several seasons. Feel free to disagree. Except 1901. That one is unquestionable. We only gave up 10 points all year while scoring 338 in 9 games.
1906(first one that's all college teams)
1912(this one honestly is more legit that like half of those claimed by Bama or Ohio University-Columbus)
So there you have it. 4 national titles. As a bonus in 1912 Wisconsin was widely considered to have the best men's basketball team, so Florida can stop claiming to have been the first Division 1 team to have pulled off that double.
