The Genius Of Bill Walsh
Every great "dynasty" (1960s Packers, 1970s Steelers, 1980s/90s 49ers, 2000s Patriots) and near-dynasty (1970s Cowboys, 1970s Vikings, 1990s Rams) of the era is represented on the list, except for the largely overrated Cowboys of the 1990s -- a group that went better than 12-4 just once.
But one dynasty loomed larger than the rest.
Three teams in the top seven belonged to Bill Walsh. This cluster of San Francisco teams proves that the great genius Walsh, as Cold, Hard Football Facts have noted, was not that he popularized the West Coast offense. No, the great genius of Walsh was that he popularized the West Coast offense while creating arguably the greatest (and certainly most underappreciated) defensive dynasty in history.
For 17 straight years, the 49ers never surrendered more than 300 points in a season and they consistently produced very low Defensive Passer Ratings, usually among the very best in the NFL. We discussed this phenomenon a couple years ago and more recently this spring, as it related to Ken Anderson's Hall of Fame cred.
The fact that three of the top seven teams all come from the same organization in the same brief period of success is amazing.
Let's put it into statistical context: the 49ers won five titles not because they had Joe Montana and Steve Young. The 49ers won five titles because they had Montana and Young and consistently paired these great passers with the best pass defenses in football.
WOW that is a great stat less than 20 points a game for 17 YEARS STRAIGHT!!!! that is almost as impressive as the offense. Wow again. we did have the best secondary ever imo in 84-86 range..and the great secondary play and defense play continued through 97...just sick.
