Hardy was drafted in the first round (eighth overall) of the 1945 NFL draft by the Washington Redskins. He played in the National Football League between 1946 and 1952. He made the Pro Bowl in 1950. Hardy is perhaps most famous for throwing an NFL-record eight interceptions in a single game, as well as for the worst touchdown pass-interception differential in a single game (-8), in a 45–7 loss to the Philadelphia Eagles on September 24, 1950.[2][3]
He later served as the general manager of the Los Angeles Memorial Coliseum.[4] In September 2016, Hardy was interviewed and reflected upon his career in the NFL. Prior to his death, Hardy was the oldest living member of the inaugural 1946 Los Angeles Rams.[5]
