In response to my email asking where I'd be sitting if I bought tickets to the Tennessee game through UConn:
"Unfortunately, I do not have that information. I am unaware of what the visitor sections are at Neyland Stadium, nor have we been given that information internally.
UConn donors, season ticket holders and alumni who buy tickets directly through us will be seated based on their donor level and priority points. All you would be doing is purchasing the tickets, and your seating locations would be determined at a later date. The tickets would be mailed to your home address 10 days prior to the game. I imagine that is when you would learn your seating locations."
Not sure if the same applies to all games.
