I have a BSJ from The Ohio University and an MEd from osu. I root for 3 teams every autumn Saturday - Ohio, ND, osu's opponent.
We have more in common than either of us would like to admit: BSJ, Ohio; MA, OSU; Ph.D, Ohio. I was told by one poster on this board that I was practically an immoral person for not rooting for OSU since I had a degree from The Big Farm, as the grad students in the now-defunct OSU J-school used to call it back in the late 1960s. I have a good friend, an usher in my wedding, who was a very good friend of the late Steve Hayes, Woody's son. Out of respect for my friend and Steve, who I got along with very well, I've been a little more muted in expressing my feelings on this issue in recent years. But at a very visceral level I still feel much the same.
In your list, I'd substitute, Marshall for UND, but I usually do root for the Irish.
