Through the season's first six games, opponents were averaging 29.8 points per game against the Eagles' defense.
Over the last four games, the Eagles and defensive coordinator Billy Davis have that number down to 10.8 after a month's worth of strong defensive performances.
Third down is still an issue, with the Birds allowing teams to convert 40 percent of the time, but the Eagles' ability to control the run game and force turnovers has made up for that number.
The Eagles are 14th in rushing yards allowed per game and eighth in the league in takeaways with 17. The run defense's best performance may have been last weekend, shutting down Packers running back Eddie Lacy (see story).
"The thing I love about Bill Davis is that he's taught his guys how to play defense the correct way," Brian Westbrook said on Comcast SportsNet's "Eagles Extra" on Monday.
"You see guys in the right gaps, doing the right thing. Whether the play comes to them or not. He has those young guys. They believe in the system, they believe in Bill Davis, and that goes a long way to how much effort you're going to show on every single play. Every single play these guys go out and show a lot of effort. If you want to be a good defense, you have to play together well and show that effort."
The Eagles are still .500 in the last month despite playing such strong defense, but the team has been in position to win games late, no matter how poorly the offense has played.
When both sides of the ball are clicking, like Sunday at Lambeau, the Eagles are free to play with a lead and run out the clock (see story).
"They're playing well together," Westbrook said. "And that's what it's all about. At this point in the season, you have to get hot, especially to make the playoffs. They've won two in a row, and that's what it's all about."
