That was half the rich kids at Lincoln East back in the 80s and 90s. They loved them some Duke.
I grew up in Germany until I was a teenager so I had zero loyalties to anything in American sports outside of.....wait for it....Michigan and Iowa....(cue laugh track). Dad's family from Michigan, my sister went to college at Iowa when I was still a kid in Germany. Never even heard of Nebraska until my Dad managed to choose it over California as the place he was going to retire (thus ensuring his divorce from my German mother...lol).
So, to shorten this up a bit, living in Bellevue in the ate 70s, I was introduced to Bluejay hoops by my stepdad and went to a ton of games before I even *set foot* in Lincoln for the first time. Yet, every football season, I'd start learning to root for the legendary Huskers as my Dad and I became fans pretty quickly (I played football in Europe before a tumor took me out of sports entirely).
So Jayskers have existed for years and years, and technically, I would have been one of them! That would change soon enough as I would become a Husker in 1980 (and still remember watching Bo Jackson try to run on a rain soaked stadium field and failing!).
Sorry for the bio, but I've always found this whole subject and animosity amusing here.
