I don't think the Chick-Fil-A is concerned with selling out the game. Haven't they done that 15 years in a row, no matter who the team is?
Bowls like the Music City, Liberty, etc are much more worried about selling out. Personally, and this is selfish, I'm pulling for the Liberty. I will be in Vegas during the Music City and Independence Bowls. I have no desire to go to Birmingham and I believe we are too far down the pecking order to be picked up by the Chik-Fil-A.
