The way I do this–I take the defensive averages from the last 3 games, and extrapolate those numbers as if the Rams had played 10 games with those stats, and determine the ranking accordingly. I then compare THOSE rankings to the actual rankings for the season, based on all 10 games.
The last 3 games are of course SF, Arz, and Denver.
