The Packers advanced to their second straight AFL-NFL World Championship Game, but had a much more difficult time than in the previous season. Both of their starting running backs from the previous year, future Pro Football Hall of Famers Paul Hornung and Jim Taylor, had left the team. Their replacements, Elijah Pitts and Jim Grabowski, both went down with season-ending injuries, forcing Green Bay coach Vince Lombardi to use second-year reserve running back Donny Anderson and rookie Travis Williams. Fullbacks Chuck Mercein and Ben Wilson, who were signed as free agents after being discarded by many other teams, were also used to help compensate for the loss of Hornung and Taylor. Meanwhile, the team's 33-year-old veteran quarterback Bart Starr had missed 4 games during the season with injuries, and finished the season with nearly twice as many interceptions (17) as touchdown passes (9).
