Its based on the expectation that for once Idalski might actually beat preseason expectations, not necessarily a national championship.
Its easy to replace Idalski with some one better. That wouldn't be a problem.
The twins didn't come to UND because of Idalski. They came because they wanted to help build their home towns womens hockey teams program.
The UND womens hockey coach situation is the reason they chose Minnesota over UND to start their college careers.
