Almost half of the Packers' "championships" were prior to the NFL color barrier being broken. Think about that. And you think this league is "watered down"?
That was an era when the virtually no one outside the Bears, Packers, Giants and Redskins won a championship for 20 years (17 of 20). What an era of parity!
The Patriots scored as many Touch Downs in OT of SB51 as the 1929 Dayton Triangles scored all season (and they only played road games). Read it twice but its true. All of three teams in the league were above .500 that season
The AFL was launched in 1960 and didn't merge with the NFL until 1970, although they started SBs in 1966. The Colts (68) and Vikings are considered NFL Champions but not WORLD CHAMPIONS since they lost the SB.
So, NE and GB have been in competition for a World Championship since 1966 with the Patriots holding a 5-4 edge.
No one every said it was EASY to win.. Just a lot easier than it is today.
