Tulane - LSU was still a big game until about the time that the Sugar Bowl was torn down in a typical Louisiana dirty deal.
Tulane was in the SEC until the mid 1960s, but the collapse of the program was well underway at that point.
I’ve always thought there should be a ‘Southern Ivy’ football conference - Tulane, Rice, SMU, perhaps TCU, Baylor, Tulsa, Vandy, Wake, Duke would be a good start.
Saw Tulane was playing Rice today in the Nerd Bowl.
