re: why doesn't louisina have another big state school that rivals lsu?

Tulane was one hell of a big rivalry when they were in the SEC. Tulane took GT exist as a way out of the SEC due to grade requirements. Both schools went independent, then joined the Metro Conference, and GT was invited to the ACC. Whoever convinced Tulane to leave the SEC needs to rot in his grave. Tulane isn't revelent in any college sport.
