I've lived in Roanoke most of my life.
Most of my high school friends go to one of the two big state schools. My girlfriend is a recent Tech graduate. I'm not arguing that their fanbase was nonexistent before. I'm not arguing that their tradition isn't weak. I'm arguing the fact that it clearly appears you haven't been to the state in at least 15 years, because most of the graduates from Tech grew up watching Vick and feel like they have a legitimate connection to the team.
The fanbase is larger and more electric now and has been growing for more than a decade. It's not going to fizzle out as soon as they have one bad year. It's expanded as far south as Charlotte and as far north as Maryland.
Virginia is as much of a UVa state as Tennessee is a Vanderbilt state. That's not changing, because UVa will likely never field a legitimately competitive football team again- they're too into academics.
