You are missing quite a few yet. Arizona State, Army, Navy, University of North Dakota off the top of my head. Theres not that many D1 hockey schools so not really sure what you're saying but many do play D1 in Basketball and football too
But in your scenario with ND not playing in a championship game to impress the committee you realize only 10 P5 teams would be doing this. And 5 would lose. This would actually benefit ND. So they would be sitting at home that week just like Penn State or Bama was this year
I have tried and tried to get friends to add on to mine or split tickets between a few. No luck. So likely just renew our 2 and hope the seat next to us will be available as our baby gets old enough
