You make a good point. But...
Everyone in the Sun Belt knows we're going to the NOLA bowl. It's a done deal. Announcing it officially will only make things easier for us to get a blockbuster crowd on December 17th. More people can make plans earlier (a necessity for a fan base that hasn't made bowl plans in 40 years).
Announcing the NOLA bowl acceptance will be Coach Hud's 5,000th coaching challenge in his early tenure at UL. Good problems to have. Good problems.
Oh, and btw, I'm not overlooking ULM! We win 48-6.
