ND is NOT a hard place to win at...ND ***IS*** one of the hardest places to satisfy the fan base at.
So in terms of how hard it is to coach here, there is some accuracy to that. But historically almost every single coach (good ones, bad ones, mediocre ones, all of em) who coached at ND and other stops, had a significantly higher win % at ND than their other stops.
