Thought I'd make a suggestion. I thought a dalmatian dog would be the most appropriate mascot for Gally as many dalmatians are deaf. Perhaps a survey can be made to find out what alumni think of the idea. Dear HR, Hmmmmm. I like your idea.
Dalmatians project a sense of speed, vitality, and smarts.
Bison do not, in my opinion. Of course, not everyone will agree with me on this. Gallaudet is steeped in tradition, and few want to give up even a smidgen of it. This is understandable, but vexing to those of us who require frequent doses of the new and unpredictable in our lives. Be sure you say your question is for Aunt Sophie.
