Wouldn't you agree that the Packer's championships won before the Super Bowl era should be considered "true" football championships in every sense? Especially considering the fact that no other league could be compared to the NFL in quality prior to the merger. And Green Bay proved this by the way that they slaughtered the AFL champions in the first two Super Bowls.
I'd say you have to distinguish between one league and the joining of two and that the SBs do that. And noting a dominant team that arguably would have been had the leagues been joined prior doesn't really prove the other league was lesser, only that, arguably, it didn't have anyone who could have competed with the Packers then either.
We both know that sometimes a team advances to represent a league that really isn't the best team that league has to offer and that sometimes the best a league has to offer stands alone in a relatively weak group (see: a down year for the SEC). Late injuries and the puncher's chance of one and dones can often advance weaker teams, as when the Bills managed it with a historic come from behind on the arm of a back-up who'd managed the same thing in college. That sort of thing happens.
As far as myself, I consider that all of Green Bay's championships are true championships which should not be diminished in any way.
I'm truly sorry that you feel my noting the 60s as theirs and representative of their dynasty was insufficient praise.
Should I order them a special trophy?
On the other hand, I cannot say the same thing about any of the teams which won the AFL championships.
Spoken like a loyal supporter of the other conference. That's what Baltimore thought too.
