8 championship is very impressive for sure, But since ND is part of the ACC I must point out that 8 championships hardly compares to the 26 that ND has won over its 132 year history in football. ND is a part member (42%) of the ACC in football after all. Duke has won 5 championships in men's basketball and North Carolina 7. I think the ACC has a lot to crow about, even though we don't crow about it, like an annoying rooster, like BBN.
Before the BCS era all football championships were mythically. You can chose to ignore them but it doesn't change history. Alabama claims the most titles now and that's fine with me. They earned it.
