In fact, I'd be surprised if they DON'T retire the Bear costume when the guy retires. Probably with a ceremony and announcement of who the guy has been this whole time.Pretty random, as far as I know. Some mascots around the league are very open about who they are and what they do. Bear has always taken great pride in making it about the character rather than the guy inside the suit. I wouldn't be surprised to see the Jazz retire the character when his career ends.
