My earliest clear memory was the 1965 NFL championship (the last of the pre-super bowl era) against the defending champion, Jim Brown led Cleveland Browns. My dad was/is a huge Browns fan. The 66 and 67 teams are are more known for the cold games against Dallas but, this one was a mud bowl in rain and sleet in Lambeau. Ironically, the best running back that day was not the two Jims (Brown and Taylor) but, Paul Hornung. However, the real studs on that day were Ray Nitschke and the defense. Here's a little help from Wiki:
"Vince Lombardi proved to be a master tactician by stressing a ball control offense, assigning Nitschke to shadow Brown all day, and switching defensive assignments when Warfield was getting open early in the game. The Packers ran the ball 47 times for 204 yards on the day while holding Cleveland to just 38 total offensive plays. Lombardi coached the team to stop Jim Brown and force Cleveland's other players to step up and try and win the game. The strategy worked as the Packers gained twice as many yards from scrimmage as the Browns."
Future Hall of Famers in that game:
Browns: Jim Brown, Lou Groza, Gene Hickerson, Leroy Kelly, Paul Warfield
Packers: Vince Lombardi (coach), Willie Davis, Forrest Gregg, Paul Hornung, Jim Ringo, Ray Nitschke, Bart Starr, Jim Taylor, Willie Wood
That's 14 future HOFers in one game!
Incidentally, does that offensive strategy sound a bit like how the 49ers beat us in the NFC Championship last season?
