Just thought it was an interesting stat that we have not had a matchup in almost 40 years where both teams had never won a Super Bowl before. Every game since then has featured at least one team having won the title before. It makes sense as the league has been around for longer, the odds of this happening will happen less frequently, but it does seem like a very long time where teams from each conference have featured at least one previous winner.
In a sense, the Los Angeles Rams and Cincinnati Bengals were both playing for their first superbowl title in 2021.
