Not sure what you're trying to get at but I'll say sure.
But the Alerus can't sell 4,000 SRO tickets to actual people though. I'm sure there's a limit to the number of people that can attend a UND football game thanks to "code." Unless of course it was still under capacity with those 4,000 people but wouldn't that be counterproductive to your point of trying to get over 15,000.
I believe, its usually its a "foundation" that buys all the "unused" tickets at the reduced rate, and they were 4,000 tickets "to the game" yet had to watch it on TV in the Ballroom.
