Oh wait, they have.
They played against them on the fast track turf at the Mercedes-Benz Superdome, and it did not go well at all for the Lions.
As great as Stafford and the Lions have been in the last month, the Saints are just too overpowering. Drew Brees is playing at a different level, similar to what we saw back in the 2009-10 Super Bowl run.
When these two teams played in the Big Easy recently, Brees threw for three touchdowns and had a passer rating of 129.6. He also completed over 72 percent of his passes.
Stafford also played well, but that's all the Lions have. They're too one-dimensional. The Saints know that the Lions are going to be passing the whole time. Last week, Stafford threw the ball 59 times against the Green Bay Packers.
The Saints, on the other hand, have three running backs who can provide an impact. Chris Ivory was phenomenal last week against the Carolina Panthers with 127 yards and a touchdown.
Throw in Darren Sproles, who is also a receiving threat, and Pierre Thomas, an experienced back, and all of a sudden it's apparent that the Saints are going to blow the Lions away.
The Lions running game is close to non-existant. They have the second-worst ranked rushing offense in the league. New Orleans knows Detroit's going to be passing so it makes it a lot easier for them to anticipate Stafford.
Stafford will get several touchdowns, but there is no stopping Brees, the Saints and their great running backs.
They've won eight in a row and some of those wins have been by large margins. In fact, their closest margin of victory in the last six weeks has been by five points at Tennessee. Other than that, they've won every game by at least 14 points.
The Saints are also a fantastic home team. Their smallest margin of victory at home has been by seven points against a tough-as-nails Houston Texans' defense. The Lions defense is nowhere near as talented as Houston's. Drew Brees should have a field day.
Finally, the Saints probably have bitter memories from last year's playoff loss at Seattle. They want to avenge that and get on a roll. They're the hottest team in the league playing with a chip on their shoulder.
This is Detroit's first playoff appearance since 1999. Unfortunately for the Lions, the Saints are going to make them look more like stray cats in an alley.
