I like it, I think we should have a live and a cartoon mascot on the sidelines. It does not need to be an albino (white) alligator, but that would be awesome if it were. I think the concept, being that we have the most unique name in college sports (Ragin' Cajuns) and then a unique actual mascot with an albino Alligator.
The other thing I would do is immediately I would copywrite "DA SWAMP or LE SWAMP". Not The Swamp, but Le or Da Swamp for Cajun Field. Florida can then have "THE SWAMP" and we would take "LE or DA SWAMP"
Le would be for the French reference and Da Swamp (for almost a Cajun French interoperation of the Le Swamp).
