The UW team was the #1 ranked team overall that year though. So while the UMN team during the HC year was good, if they would have beaten HC, they then would have had to beat UND at the Ralph, won the F4 semi-final, and then beaten UW in Wisconsin. Not an easy feat.
The flip-side to this debate is that while some teams are great and end up not winning the title, there are always the teams that were dominant all season and take home the hardware. Just look at BU last season.
DU is good. They're not as dominant (yet) as BU was last season, but if there was a short list of teams you would expect to see in the title game, DU, UW, Miami would be on it. That said, I would love to see all three of those teams come up short.
