Crowding out the NCAA's?

Chris Myers(No, not that one) of 1500 ESPN in the Twin Cities is reporting that the arrival of both the Big Ten Hockey Conference and the National Collegiate Hockey Conference, not to mention the permanence of the WCHA, may make it unlikely, if not prevent outright the NCAA hoops tournament from ever considering the Twin Cities for 2nd/3rd round games ever again(Unless the Metrodome or whatever replaces it is available).

If this is indeed the case, the NCAA's promise of early round action may go unheeded, but simply because the arenas in question have chosen to go the safe route of guaranteed attendance, rather than having unfamiliar audiences.
