I don't buy Minnesota to the Rose at all. I believe the criteria said they can pick whomever in the event of a cluster of teams that were ranked within a few spots of each, which Minnesota is not. They are 10 spots below Wisconsin and 8 below Penn State currently. There could be some movement after the games this weekend but not much.
Additionally, the only way the Rose would not select the highest ranked team is if they did not want a certain team, which seems like it would be the case if Minnesota was the highest ranked. I think we are kidding ourselves if we believe the Rose would select a team over another because of head to head victories or things of that nature. They want the best matchup that will make them the most money and sell the most tickets. Minnesota sold out the Penn State game (the biggest game in the last half century at the time according to their fans) one day before the game... for a 40k capacity stadium. Sure, some Minnesota fans would travel for the Rose, but there is no way they'd match Wisconsin or Penn State's traveling fan base.
