It's not conclusive but it certainly is evidence he doesn't hate the Gophers.
Many people who are Gopher athletic fans are fans because of similar connections - they attended the U, their kids attended the U, they have some relationship with the U.
Do you think someone whose kid went to the U of MN is more or less likely to be a Gopher fan than someone whose kid didn't?
Do you think a Gopher fan is more or less likely to donate to the U? If you were going to donate to a school for cancer research, would it be more likely to be the U or Madison?
Your example is also the exact opposite of Shaver's situation. As you said, Winnebago JUST relocated. Randy didn't JUST relocate. He's lived here 40 years, raised his kids here, donates to the U, his kid went to the U.
Your Winnebago comparison would be more like the kid who lived in Iowa his entire life and moved in Minneapolis a month ago. It is, literally, the opposite of Randy Shaver's situation.
(I have no proof of anything with Shaver. This is hypothetical discussion for the sake of discussion. Probably didn't need to be said, but wanted to make that explicit.)
First question: are you asking me if a person who went to Iowa or Wisconsin, then moved to the Twin Cities for work, built a career and raised a family here, and their kids went to the U is like "I've been a Hawk/Badger fan since (before) undergrad, but 40 years later my kid graduated from the U, so now I like the Gophers instead!"
It baffles me if you really believe that can be true.
Second question: it was mentioned that the
Shaver Foundation donates to the U Cancer Center. ....... Where else would they donate?? You can't possibly tell me that a guy who has been a public figure in the Cities for many years is going to tell his foundation to not donate to the local group but to Wisconsin and Iowa instead?
That's not a thing. (I have no idea if
he, personally, donates to the U (Cancer Center). That would be a much different thing.)
You posed the question of if a
Gopher fan would donate to the U (Cancer Center) or Wisconsin. But that's assuming the thing that is in question, first. We don't know if he is a Gopher (athletics) fan.
