Until we can not only sell out the arena but actually have the seats fully occupied for all B1G games and at least all mid majors and up, we don't need to ruin the atmosphere by putting in a couple thousand more of the least occupied seats.
Leave it as it is unless we can consistently sell and occupy the current 300 level seats for perhaps 3 to 5 years.
If we do that, it means we have had success. Perhaps then and it will be time to expand.
Before that time, we should strive to make Husker PBA games a very tough ticket.
