This spreadsheet takes a look at the Super Bowl/NFL Championship game matchups that would still be possible today under the current NFL playoff format, as well as which matchups have already happened and which ones haven't yet happened.

Out of the 256 potential Super Bowl matchups, 50 of them have occurred so far.

The most common matchup out of the ones that could still be possible to re-occur is the Cleveland Browns v. Detroit Lions, as the teams have faced each other four times, coming in 1952, 1953, 1954, and 1957.
