Having worked at TMS for Nascar events, I just don't see how anyone involved would enjoy this scenario. I see an abundance of issues with the facility and it's ability to host a football game:
1. Many of the infield structures (garages, media center, scoring tower,etc) are permanent structures that would have to be worked around to put the field in. How could this work and not obstruct views of those in attendance?
2. The facilities are dated and there isn't anywhere that I've been that would accommodate locker room facilities for the teams.
3. Seating itself wouldn't be a good experience for attendees. Even the best seats would probably be 100+ yards from the action.
I miss the annual meeting between the Horns and Aggy, however, this is not a good idea in my mind. You have to hand it to TMS though, coming up with new ways to generate revenue since they aren't making near as much money in recent years because of the attendance decline at racing events.
