Maybe I'm somewhat bitter, but I'll always argue that both Chattanooga and ETSU have a somewhat impossible task because UTK monopolizes the college football "product" in East Tennessee. And I don't mean that from a talent standpoint, but mostly from a fandom standpoint. Not sure how it is over in the mid-state, but we absolutely marginalize ETSU, Chattanooga, Carson-Newman (post Ken Sparks), Tusculum, etc in this time zone. I've seen my wife get ridiculed on multiple occasions at the grocery store for wearing an ETSU alumni shirt as opposed to orange/white on Saturdays in the fall. I certainly understand why I get a hard time for wearing my Buckeye gear around here, but give me a break.
There are plenty of states that have perennially successful FCS, D2, and D3 football programs. Tennessee just isn't one of them. It certainly would help if the residents of the tri-cities would collectively get behind ETSU. That was part of what killed the program in the first place. I take my wife and kids up to Johnson City to support the program, but I'm still not entirely convinced that the local communities have bought in. I've had multiple folks tell me that more Johnson City residents will make the drive to Knoxville for a Tennessee game rather than attend an ETSU home game. Not sure if the same is true at Chattanooga, but that wouldn't surprise me.
