In 1923, after seeing the University of Wisconsin football team carry live badgers at games, University of Michigan athletic director and football coach Fielding H. Yost decided to procure a wolverine. Despite writing letters to 68 trappers, Yost was reportedly unable to find a wolverine. The best he could do in 1924 was to obtain a mounted and stuffed wolverine from the Hudson's Bay Company. The stuffed wolverine was named “Biff” and was featured on the cover of a 1925 game program, along with team captain Robert J. Brown straining to hold Biff on a leash. The caption to the photograph read: “Capt. Bob Brown and Biff: The Wolverine Mascot of Michigan Athletic Teams Is Noted for Its Ferocity and Gameness in Battle, a Characteristic of Every Team that Wears the Maize and Blue.”
