I tend to agree with you on UNO. They are kind of like Denver, in that due to the hockey relationship, Sioux fans feel like they should have that angle to get games with them, but they never materialize. We have never scheduled them since we left DI. All three games are the result of either the Bracketbuster or the CIT.
I have been more perplexed by the absence of USD on the schedule lately. USD may have a few more options, geographically speaking, but still they need DI home games too. Have to think North Dakota would be one of the most attractive non-conference home games they could schedule on a regular basis. NDSU, SDSU, and USD can basically all guarantee themselves one non-conference DI home game every other year in perpetuity.
