Everyone down here loves LSU. It's nauseating how passionate these people are for the purple and gold. I do give them credit for having high standards.
It seems the shared Catholic affiliation between ND and the high schools has very little influence. The Catholic schools heavily favor LSU and to a small extent the other SEC schools. ND is an after thought and isn't take very seriously by 99% of the population.
Perhaps this is because ND went a decade between beating SEC teams (span included 2 SEC blowout bowl losses)? Winning like yesterday will only help.
