I struggle with this question. When I answer this on the football and basketball boards, I don't grade them on the "good by Minnesota standards" scale, I grade them on the expectations I would set for a random major conference team. If those are the standards, I think it has to be a B. Only 8 teams in the country get to play deeper into the postseason than we do, and we did get to hang a conference regular season and tournament banner.
If I do put us on the "Minnesota standards" scale, that obviously has the opposite effect of what it would for basketball and football. When I consider what this team was capable of and the talent they have, I give them a D. As bad as it was, it could have been worse. We could have folded up shop when we were sitting on the outside looking in in the pairwise rankings and missed the tournament altogether (that would be an F). Instead, we went on a pretty dominant late season run, and reached the tournament before refusing to exert any effort once we got there. That was embarrassing, but definitely not the worst case scenario.
