Interesting...looks like part of their ranking was pts earned (wins 2 pts, ties 1)...they must have placed some weight based on 'competition faced/league you play in' as well. Notably, Union has 51 pts and is ranked below teams with fewer points; Dartmouth's 33 has them ahead of teams with more points. The Gofers are given a 25% chance of making this tourney; I'm pretty sure the only way they make it is if they run the table, and do very well in the Final Five or win the Final 5.
It would be interesting to know the criteria used to make this. Personally, I don't take a lot of stock in any prediction that gives Yale a better chance than Boston College of winning the NCAA's.
