There is no flawless team in this NFL season. The Rams are undefeated, of course, but Sunday was the first game of the season in which their defense delivered the sort of dominant game we might have expected heading into the year. Before this week, no team ranked in the top 10 in both offensive and defensive DVOA. Last year, five teams -- the Saints, Rams, Steelers, Vikings and Super Bowl champion Eagles -- pulled off that feat.
All of those teams are in the postseason discussion this season, but none has been as consistently effective on both sides of the ball as they were in 2017.
