The American Wrestling Association of Minneapolis popularized wrestling, fed many personalities into later leagues, and is responsible for all of the variants we see today. I dislike wrestling, but Minnesota played a huge part in its exponential growth. If so many Minnesotans had not watched the AWA on Channel 9 on Sunday afternoons in the 80s, theatrical wrestling would have never taken off as it did.
As for the Gophers, college football has become a staple of the South. Football talent, as a general rule, is not going to end up in Minnesota these days. And that's fine, NCAA Division I football is the biggest con in sports. I doubt anyone wants the UofM to turn into the University of Texas or Texas A&M anytime soon, where the tail wags the dog and the megadoners for the football program shape the priorities for the entire university.
If memory serves, Gophers hockey had a nice run of dominance around the turn of the century.
The Minnesota Kicks were a popular, exciting, and successful team for the short time they were around before the league collapsed due to mismanagement.
It was not until the 2000s when the LA Lakers won more championships in LA than they won while they were in Minnesota.
Did we forget about Minnesota Fats? He was magical.
