Who have one exactly 1 consensus title and 2 total claimed in 70 years. Like ND, they have not played well in the playoffs or BCS bowls until last year, when they had to cheat to do it.
ND has either played in the BCS championship game or finished Top-4 to make playoffs 3 times in the past 15 years. They were clearly a cut below the eventual winners who beat them all three times, but those Clemson and Alabama teams also annihilated the teams they played in the final worse than they did ND. ND earned all three spots.
ND has outperformed and out-developed nearly every other program in the past 15 years not named Alabama, Ohio State, Clemson and Georgia. LSU is a Jekyll and Hyde. ND is right around Oklahoma and Oregon, and nobody would say they aren't NC institutions.
Long story short, Michigan sucks and they just won a title.
