Yes.
All throughout rural GA, you see UGA stuff in the yards and on vehicles. Almost none of them went to UGA. But the Dawgs were THE representative for that area for decades before any pro teams showed up. The Braves are an institution, but the Falcons (as Cincy said) are not. But the Braves were on TV every day on most every television. And they had sustained success.
Same with the state of FL. The Dolphins were big for a time, but not so much since Marino retired. The Bucs and Jags are 'meh' in the state consciousness. FSU stuff? Plenty. Gators stuff? All over. You'll even see like 3 Canes stickers if you tour the entire state.
People don't realize that all the red areas on political maps are largely college fans, as pro sports tend to belong to and are contained within the big cities (GB notwithstanding).
Good ole state U.
I probably struggle with realizing the appeal of the NFL because of this. I grew up pretending I was Barry Sanders and Emmitt Smith (OK State and UF versions) on the playground. It was super cool to live in Jax as the team was formed, but I wasn't dying to go to Jags games.
Hence 90,000+ every Saturday in smaller college towns > 65,000 in big cities on Sundays
