It can obviously be done to an extent.................the men and women played all of their NCC conference games in the REA in 2004-05 and 2005-06.
I'd prefer they stay in the Sioux Center, save for when they host NDSU, and possibly down the road if a rivalry develops with a Big Sky school (perhaps Montana or Montana St. ? ) that would consistently be able to sell 5,000+ seats for such a game.
Aside from that, I'd consider it a remarkable accomplishment if UND basketball ever averages 3,000 per game again, and the Betty can accomodate that. 3,000 in the Sioux Center is a great home-court advantage. Even 5,000 in the REA is not.
Coincidently, Sean Johnson addressed this very subject on Friday on the Christopher Gabriel Program when asked about the several much larger basketball arenas in the Big Sky Conference. He had the same company line answer that the Sioux Center needs to get full before they think about a different home for basketball, but if it did happen that either the REA or the Alerus would be the likely options.................
