I think it's important to point out UNI won that game by 20, not on some sort of last second bad call. The MVC assigned officials that day, pulling largely from the same pool as the B1G, and as has been pointed out, Higgins has worked several final fours --- regardless of how you feel about him as an official (and UNI isn't always happy with him either), he's considered one of the best.
Also, on the ESPN 3 thing, yes, the MVC does have a contract with ESPN and Drake was the "host" school this year. But, last year UNI was the host and the Iowa/UNI game was still on the BTN. These sorts of arrangements can be worked out by the networks if they want to.
From this UNI fan's perspective, I'd love to go back to the home & home series. Short of that, we grudgingly accept the Big4 thing, despite the fact UNI is the furthest from Des Moines and has the smallest fan base in the capitol city of the four schools. UNI would not entertain any option of only playing in Iowa City/Ames. That is not something we do. We don't take "buy" games like low-major programs do. If Iowa were to choose to end this event and basically stop playing UNI & Drake, I think the state's media and public would see that as being weak.
