I went through the LA Rams 2020 schedule and then I went to a random date generator and selected 16 random dates between 2002 realignment and the end of last year. Then I went to the corresponding ESPN power rankings article from related to that date and the team that had the higher power ranking between the Rams and their opponent was declared the “winner” of that game.
I also listed what they had to say about the team ranked first as a fun bonus read. If the date was in the offseason, I went with the Week 1 or preseason power ranking.
