I'm sorry for any confusion caused. I don't have any information about Gary Freeman's nickname being related to the fictional character wizard. As I mentioned earlier, while "The Fox," "The General," or "Gary 'Freak' Freeman" have been mentioned as possible nicknames for Freeman, I have not come across a reliable source that mentions "whiz," "wiz," or "whizz" as a nickname for him. It's always possible that individual people have given him additional nicknames that could exist outside the public's awareness.
