This is from the List of NFL champions (1920–1969) article, talking about the first four Super Bowls --
"Teams winning the NFL Championship during these years move onward to compete in the first four Super Bowls. The Green Bay Packers continued on to win the first two Super Bowls. The latter two teams, the Baltimore Colts and Minnesota Vikings, lost in their respective Super Bowls. These two losing teams are still credited with the NFL Championship in their official record. However, they are not considered as world champions, but as the less prestigious league champions."
And though it was less prestigious, it was still a league championship. This has been the standard for all the years I have been editing NFL articles. If anything, the standard has been not to count Super Bowls I - IV in total Championships. Don't you agree that if you are going to make this the standard, then you should change all the other articles showing KC, OAK, BALT and Minn as league champs from 66-69? And we are talking about a lot of changes to get to your standard of not counting these titles. We know this is not happening, and we should revert back to showing the deserved league titles as it has been for years. Thanks. I am posting this in each talk page on each template so others can give their input. Spparky (talk) 19:37, 19 August 2018 (UTC)
