You could make that argument for Minnesota St.
But the rest of those schools, including Wisconsin and Michigan, have played schedules as difficult, if not MORE difficult, than any of the Hockey East schools.
That's the problem. We don't know who is playing the more difficult schedules because there aren't any out of conference games. The lack of crossover is leading to a bunch of assumptions in the rankings.
Normally, the rankings mean nothing because the tournament is selected via the PWR. That's out the window this year though because everyone is in conference.
