The Carolina Panthers have been the story of the N.F.L. this season, easily surpassing preseason expectations on the way to a 14-0 start. But after Carolina’s loss at Atlanta on Sunday, the Panthers are not going to become the first N.F.L. team to finish a season 19-0. Even so, that does not mean there is not a historically dominant team this season. It just happens to be a different N.F.C. team.

The Arizona Cardinals lead the league in scoring, with an impressive 32.2-points-per-game average. The team ranks fourth in points allowed, at 18.5, and, if things break Arizona’s way in Week 17, it could wind up leading the league in that metric, too. More impressive, Arizona has outscored its opponents by 206 points, or 13.7 points a game. That is the third-highest margin of any team in the last 10 years, behind only the Patriots in 2007 and 2012. From 1970 to 2014, only 17 teams have outscored their opponents by such a margin; eight of them wound up winning the Super Bowl.

There is no secret to Arizona’s success: The team is simply dominating in nearly every facet of the game. The Cardinals have outgained opponents by 1,508 yards this season; the only other team with an edge of even 900 yards is the Seahawks (1,267). Arizona leads the N.F.L. in ancillary statistics, too, like third-down percentage (47.3 percent) and time of possession (32 minutes 38 seconds per game). It ranks second in takeaways with 33.
