Offseason
Yoder's top assistant Brad McNulty, suspended without pay since August 1, 1989, was fired just prior to his eighth season at Wisconsin for billing personal phone calls to the university from January 1988 to May 1989. McNulty made 51 calls to Nevada hotel casinos, which cost the university over $2,000 and resulted in a felony charge.
