Meh the Packers have some legit history, though you should discount anything in the nfl before the 50's really... they still have like 7 or 8 championships, but those 30's championships are meaningless.. many were pre championship game, there were few teams, and teams didnt even play the same number of games. Many folded mid season. The draft even start till 36 so teams through the start of ww2 were build unfairly and through 45 most players were shipped overseas to the war.. the NFL product really wasnt anywhere near professional until the 50's
Claiming those pre 1950 championships is like proudly displaying a kindergarden diploma lol.
They were a great dynasty in the 60's and had a couple runs in the 90's and 2010.., basically us with some meaningless window dressing..
