Tulane’s game with LSU had never even crossed my mind until you brought it up right there. It’s compelling from an ACC standpoint, but I’m not sure LSU would bite on it. Tulane beat LSU 5 times from the end of WW2 until 2009 when the game was halted. That’s good for a record of 5-56-3 since 1945. Should Tulane get into the ACC, LSU would probably balk at the idea of playing them just in case they lost. Maybe they could make it a big enough event at the Superdome where they would make enough money that they felt the reward was worth the risk, but I doubt it.
Getting into the NOLA market would be cool, but just like UGA and Atlanta, Tulane really has no control over that market. Their stadium seats 30,000 (1,500 smaller than Wake’s capacity) and it’s rarely ever full. It sold out when Tech opened it up in 2014, but has only had announced crowds greater than 25,000 seven other times, and hasn’t sold out since. Although, I’m sure the novelty of a NOLA trip for bigger ACC opponents could get more butts in seats more consistently. Also could help if more money helped get the program back to a more recognizable state.
For current G5 schools, Tulane is the only one that I would personally not be disappointed with as an addition. I don’t want any part of UCF, ECU, Cincy, UConn, Navy, etc.
