scUM.
Their fans are the most obnoxious on the internet, IMO. Even worse than the worst, most uneducated portions of SEC fans.
It also helps that they got their miracle, generational coach, despite not really deserving it, while ND kind of flounders trying to hit the "reset" button.
They catch unbelievable breaks in their (weak) yearly schedule, and they do the bare minimum against said (weak) schedule, and still get all kinds of credit.
They return NO ONE this year, and yet they're a top-10 team already? They could end up being a top-10 team under Harbaugh, sure, but they haven't proven anything. They haven't even won a truly "big" game under Harbaugh yet.
Notre Dame is over-hyped some years, but they are under-hyped other years; it generally evens out... it feels like scUM always gets the benefit of the doubt each year, even under Hoke when it was clear they were bad, and yet their fans are the first to shout about how "irrelevant" ND is, and why they're overrated.
Also, there's the whole "all-time wins" and "winning percentage" battle (which BK may have ruined).
Finally, their most famous coach was largely a disappointment, when you're viewing him in the lens of college football history as a whole. He was also a racist and bigot, and is the reason ND didn't, and will never, join the B1G. And yet scUM fans like to shout that "ND thinks they're better than everyone, that's why they won't join a conference."
They're a football factory masquerading as a school that puts football players through a rigorous education, when really they're just a bunch of bullshit Skunkbears, milling about at Walmart together between games.
Fuck michigan.
