The Rams championships were in 1945, 1951, 1999, and 2021. There were only 10 teams in 1945 and 12 teams in 1951. We now have 32 teams, which means that a team would be expected to win a championship every 32 years on average. There were gaps of 48 and 22 years between the Rams' most recent championships. It wouldn't be surprising if they don't win another until 2045 or 2055.
