I understand your point about the gator but if you design it different (i.e. different color, different look, etc.) I don't think that people would confuse it. Think about it. Their are plenty of bulldogs out there and no one confuses them. So while I like both mascots, I would rather the bullgator but I would in no way be opposed to the catahoula. We will discuss more over a beer at Legends in about 30 mins.
Also, if you are worried about fan interaction with the Catahoula.....I guarantee he would do more for the crowd than our current mascot who just sits down with the cheerleaders.
