There are plenty of incredibly talented teams in the history of the NFL that did not win the Super Bowl.
But which one was the best?
Last week, ESPN ranked the best non-championship teams for all 32 NFL franchises, and their process wasn't a subjective one.
Here is the basis for the methodology:
"Ratings are based on the actual scores from all games the regular-season games for each team and represent the degree to which each team is better or worse than the league average of that season. What matters is who you beat/lost to and by how much, and how good that opponent was based on who they beat/lost to and by how much, and so on."
Using that ranking system, the best team to not win a championship was the 1968 Baltimore Colts. Despite a 13-1 record and a roster stacked with Hall-of-Fame players _ including legendary head coach Don Shula _ the Colts were upset by the American Football League's New York Jets and quarterback Joe Namath in the 1969 Super Bowl.
