The only game all year they played "D"! They had a mediocre at best defense all year. Not knocking the Saints, kudos to them and all that, I'm just saying you don't have to have a 1985 Bears or a 2000 Ravens defense to win it all anymore. Only 1 way to win a football game, and that's to score more points than the other team, and I think you'll see more teams like the Saints who just march up and down the field, and don't really worry about how many points the other team gets. The NFL is changing, and it sould be an interesting season.
I was curious if offense or defense had better success, so I checked the numbers.
Of the top 12 NFL for Total Defense (which is yards allowed) in 2009, 8 made the playoffs. Interestingly, 8 of the top 12 Offenses made the playoffs.
