We went to the SHHS vs Bradley Central 1st round game last year. On a cold, misty, windy night in Johnson City I'd say the total fan count was 400 or less, excluding the bands and cheerleaders. IMO it's a combination of a couple of things.....
* More entertainment options than ever. Unless you have kids or other relatives playing, high school football is simply a form of entertainment and there's a lot of competition for your entertainment dollars.
* Consolidated schools have taken away some great local rivalries and created in some cases longer travel plans than people want to put forth the effort to make.
It's not just a TSSAA problem. We watch a lot of high school football across the Southeast and while many of the community based schools will still pack the stands, there's a lot more that struggle to make anything at the gate.
