Back in 2012, I wrote a blog post indicating the most-played opponents for each Wyoming high school football program.
But over the past 11 years, a ton more games have been played. Some series have been discontinued, while others have had significant additions to their lore.
A few series have even cracked 100 games, with the rivalry between Torrington and Wheatland scheduled to become the latest addition to that group this season.
Here are the most-played in-state opponents for each Wyoming high school, entering the 2023 season, with their series record in parentheses:
