Look at their record in the NCHC. They are at or near the bottom every season. They changed coaches a few years ago and that hasn't changed anything either. I think the 2009 team was an outlier. It is a shame they couldn't close the deal after getting so close.
No, I would not be the first to be calling for changes. A young team struggling is normal, a team with a bunch of veteran players struggling is a lot harder to accept.
