There's no questioning the prowess of the New Orleans Saints' offense.

With quarterback Drew Brees leading the way, the Saints rank first in the league in passing yards, and second in points scored.

The concern about the Saints has always been their defense.

In the first half of the season, the defense did little to alleviate those concerns. But things have changed over the last four games.

Sure the Saints have allowed more than 400 total yards in back-to-back games, but they've improved tremendously in the red zone.

In a November 6 win over the Buccaneers, the Saints allowed only one touchdown.

One week later, in an overtime road victory over the Falcons, the defense gave up only two touchdowns.

After a bye week, the Saints defeated the New York Giants, 49-24. In the game, the Saints allowed 465 yards of offense to the Giants, but gave up only one touchdown through the first three quarters.

Last Sunday, again the Saints allowed 466 yards of offense in a 31-17 win over the Lions, but held Detroit to only two touchdowns.

If New Orleans only allows 17 points in a game, it's going to be awfully difficult for anybody to beat them, which is why the Saints are beginning to turn heads during their four-game win streak.

The offense is what makes the Saints good. But a good defense is what could make them downright scary.
