Nothing really, just the same anecdotal evidence of the posters saying 20k. No real reason, just an acknowledgment that 7k would be huge for an away game. I've watched the Vols play at GA, FL, SC, MO, KY, Vandy, Ole Miss, Oklahoma, TX AM, and Oregon among others, and the only game that came close to 20K UT fans was Vandy. I'm also taking into consideration geography and travel time (Knox about 7.5 hours), a smaller alumni base in that area, and the opponent. 20K tomorrow would be quite the showing. Given their stadium capacity is 68,000, 20k TN fans would be roughly 1/3rd of all fans in attendance (if the stadium is full).
