They killed Minnesota football when they took it off-campus 30 years ago. It won't be back any time soon.
And Minnesota sports fans are among the most fickle I've ever seen.
I would tend to agree, but MN FB was lacking 30+ years ago too when their stadium was more or less on campus. There was a time when MN FB was up there with best in the B10, but that was 50+ years ago.
I do think part/most of the issue with Gopher FB is their campus environment and that's difficult to fix.
