While I don't disagree with this, I don't think it's true of most Gopher fans. In some ways, it almost couldn't be true of us (we wouldn't have stayed fans). You can look at the optimism and excitement about the basketball in January or the football board in 2018. We will rally behind our teams and we are probably as big of homers as anyone. I mean that in a good way, being a homer is fun.
That said, we don't have the most successful programs and I do think sometimes we can have a bit of a chip on our shoulders where any slight or disagreement is perceived as an absolute trashing. I think, at times, we are overly protective of "our own".
For me, I liked a lot of what I saw in year 1 of CBJ. Despite the record, I am more excited about the future of our program after year 1 than I was when we hired him. He, at least partially, converted a skeptic in the middle of a last place season.
That said, I disliked how he handled our bench last year and I think we need to add more wings to this roster. I see those things as negatives so far and when I've articulated those things, there are folks on the board that react like I'm constantly trashing him.
I think supportive and positive fans can point out things they don't agree with or criticisms in general.
(PS: the same can be said about PJ, I think he's a great coach but I hate how he uses the RBs)
