The NCSS was cancelled due to money - not fan enthusiasm as claimed. You want to know what's bad for fan enthusiasm (both at MN and around the state)...replacing heated rivalries with UMD, MN State, SCSU, BSU, UND, Denver, etc. with milk toast Notre Dame. Now I sense that you're going to say that one has nothing to do with the other...and when you do, I won't reply.
The NCHC was a panic move by some schools because of a feared recruiting advantage of the B1G. The CCHA(+UAH) and the WCHA would have been fine and the buildings (and coffers) would be fuller.
