RTW, I'm not disagreeing with you and your point's very well-taken, but I suspect the issue has less to do with organization/getting the word out and more to do with NCAA Watcher's point about UNH hockey not being "must-see" any longer.
RIT was experiencing the high point in the history of their program. When was the last time UNH entered the NCAAs with anything resembling momentum? 2005? 2003? They'd secured one point in the final weekend vs. BC and lost 1-0 decisions two straight nights at home vs. Vermont.
The way the UNH program performs is that they put together very solid regular seasons, which build expectations that are then dashed in the HE playoffs. (Note that there were more rival HE fans on this board who expected a UNH FF appearance than there were UNH fans this past week.)
And this is the problem with the "UNH has made the last XX NCAAs" argument in defending the status quo. It's true, and it's valid, and I applaud them for it, but fandom isn't about stats -- it's about that gut-level enthusiasm that hasn't existed for the UNH program in many years because hardly anyone who follows the team really believes it's building toward something better.
So they enter the NCAAs on a down note every year, usually losing to a lower-ranked team in the HE playoffs, which leaves fans frustrated. So the enthusiasm isn't there for the regionals. Then they lose in the regionals, as they have for the last eight years, and fans' feelings are confirmed. And then the cycle repeats itself the following year. Fewer and fewer fans are willing to spend the time to see the same play they've seen over and over. They know Hamlet always dies in the end and they'll catch it on ESPNU rather than invest the time to see it in person.
(BTW, Dover4345: I think your criticism of Watcher is really unfair. I may be out of the loop, but I don't think he's friends with the staff. He just diligently follows recruiting in the news. And his criticisms of the program have been consistent and logical at least going back as far as 2002, when he was one of the first to lament UNH's failure to turn a Frozen Four, Hockey East tourney-winning season into big recruiting successes -- a failure that has contributed to UNH's decline over the past 6-7 seasons. He was right then and I think he's right now.)
