The Packers did win three championships in a row but that was before the merger between the NFL and AFL.
That is now the chink in the armor of the NFL so that now they say. “No team has won three in a row,” with the caveat, ‘since the merger.’
yes. memory (of a pop-warner football kid back in the 60’s) confirmed. see my comment #26. ‘Superbowl’ is just a fancy name for the NFL football championship game, imho.
