I keep hearing how UND is a bunch of goons. So I looked at the national statistics and this is what I found. Interesting, but UND isn't a bunch of goons and is taking about two minutes less per game in penalty minutes than the golden boys from Minnesota. Breaking it down even further, the Fighting Sioux are taking less penalties than Michigan, Boston University, Yale, North Eastern and Denver University.
