Other than the fanbases of the two schools, I'm not sure either will get much love from anyone.
We're both hated for the same reasons -- huge success, sustained over decades. We've both had extended dark periods, and enemies of both programs thought we were both dead and buried. Then, both experienced a resurgence, and the rest of the college football world is worried.
But because of the SEC fatigue that other conferences and even the "neutral" talking heads don't even pretend to hide any more (look for multiple replays of Dial'***** on Murray, along with criticism of the SEC office for not suspending him), I think ND will have more fans nationwide than we will.
Michigan, Michigan State, USCw and tOSU fans might half-heartedly root for us, but they really wish the whole stadium would just implode on both teams.
SEC rivals? Fuggeddabowdit. They might root for each other, but when it comes to Alabama, they wish us nothing but death. Might get some genuine love from Oklahoma or Penn State fans, but that'll be about it.
