Teams survive. None hit harder by sanctions than SMU took them like 2 decades to get their act together. And Tennessee has little competition in their state. NCAA has to be careful not to cripple an entire State.
Jmho
It wouldn't cripple the whole state. The Vols are big in the state, but so are a lot of other teams. Tennessee is a unique state. It shares a border with 8 other states. Add in that it is a narrow state north to south, a person, no matter where in the state they live doesn't have to drive over maybe 50 miles to be in at least one of those other states. Here in Chattanooga, the local TV stations are considered the local stations in cities in N. Carolina, Georgia, and Alabama.
