I don't know that it needs to be married to a single facility. Even the X is only really travel convenient for 3 of the 8 league schools, so attendance is going to be a challenge. The nchc could do like the ACC basketball tournament and have a primary site but also move around once in a while. Maybe every third or fourth year try the Pepsi Center or Cincinnati or maybe even Kansas City. Throw a bone to some of the schools that aren't in the Twin Cities' backyard.
I'd like to see the league really embrace the N in NCHC. Playing the league tournament solely in MSP may be a parochial approach and does little to develop or grow the game. There is creativity in the league office as evidenced by the college hockey showdown. I think they will come up with a good solution.
