Perrault was hated by many Husker fans in the area for one reason: he wasn't one of them. He didn't bow down and kiss the ring of all things Husker like he was expected to do. Sometimes he told it like it was, and over the past few years that wasn't always kind to the Huskers, which ticked off more than a few. It wasn't like he was making stuff up or just trying to get under anyone's skin, he was just stating an opinion.
Perrault was anti Callahan and Pederson. He has been pro Nebraska football since Pelini was hired. What has riled up many Nebraska fans is the fact that he is often critical of Doc Sadler and Nebraska basketball. Most Nebraska fans realize Nebraska basketball isn't great, but think Doc Sadler has them going in the right direction.
I personally think Perrault did a nice job in Omaha and I think he would be a great fit in Des Moines.
