In 1970 the Pro Football Hall of Fame tasked their voters to choose All-Decade teams from the 1920s through the 1960s and they added teams at the end of each decade ever since. However, the Hall of Fame is not the only organization that chose All-Decade Teams. Research has yielded quite a few more, including Football Digest, College & Pro Football Newsweekly, Pro Football Monthly all released their selections at the time, while other publications or books took a shot at selecting their own players. Pro Football Chronicle, Sunday Mayhem, and even a website Pro-football-reference.com selected teams long after the fact to broaden the field of players who excelled during each decade.
Below is the combined choices for the 1970s of those publications, and more, references and key is below the chart.
