because you are talking apples & oranges.
Some Champions were just givien by best record (sort of)
Then they went to just a Championship game.
then to one playoff game (once they created divisions or conferences) to see who plays in the Championship Game.
pre super bowl era teams often played different amount of games. Some playing a lot more or less games.
Also didnt include ties. the game is like it didnt count. one year a 6-1-6 Bears were made Champs over a 10-3-1 Packers because ties didnt count.
Bears 6-1 over Packers 10-3.
Superbowl era jumps from 14 teams to 26 teams & a whole playoff system with a more structured rule set.
So pre-Superbowl era is apples & oranges different from the Superbowl Era.
Its still called history........And you cant change history because of rule changes.....Theres no taking it back....
They dont change personal records because of the rule changes after all these years,so not sure why a person wants to exclude the 44 yrs of the NFL before the SB started.........
I think it is what is.......
