I’ve been to Duck games (ISU buddy moved there after graduation) and I don’t think they’d be a good long term fit. Buddy and I would go see a game in Autzen and wear ISU colors and receive derision and aggression. Ok, sure, I’m not wearing green, but do you have to be angry about it to the point that you call us out and make it an issue?? It happened on several occasions. We’re like WTF, we just like the game day experience and we like our team so how hard it is to deal w/ two numb nuts spending money in your stadium? I can’t imagine calling out a fan (from another conference) in Trice. I would be like “dude, thanks for coming to see our badass tailgate experience - come again w/ more friends”.
So, long story short, Oregon (fans, administration, cheerleaders, etc) would always feel they deserved the Big10 and would bring a lot of distain - they’d always be looking to bolt - like Texas.
