GREEN BAY, Wis. -- Outside linebacker Terrell Suggs was in no mood to talk about the significance of the Baltimore Ravens' third shutout of the season after Sunday's 23-0 win over the Green Bay Packers.

"It don't mean s--- if we don't make the playoffs," Suggs said. "It's good. But if we don't get in, y'all won't remember [the shutouts]."

Recent NFL history suggests this defense can do more than carry the Ravens to the postseason.

Baltimore became the fifth team in the last 30 years to record at least three shutouts in a season. Three of the previous four -- the 1991 Redskins, 2000 Ravens and 2003 Patriots -- won the Super Bowl.

This will certainly raise eyebrows because the Ravens are 5-5, currently hold the No. 6 and final playoff spot in the AFC and have been as up and down as any team in the league. But consider this: Baltimore has three shutouts and the rest of the NFL has four.

If defenses truly win championships, the Ravens must believe they have a shot.

"It’s hard to put into words because we’re in the moment right now," safety Eric Weddle said. "I’m already thinking of Houston [the Ravens' opponent on Monday night]. It’s kind of hard to sit back and enjoy what you just did. Where we’re at in our season, there’s no time to rest on what we just did. We’ve got to get ready for Houston. If we lose that game, it means nothing. But when you sit back and look at what we accomplished today, it was just a total dominant effort and timely plays."

The Ravens talked all offseason about the defense's potential to become "legendary" and rival Baltimore's historic 2000 defense.

With five turnovers and six sacks Sunday, Baltimore became the first team to shut out the Packers at Lambeau Field in 11 years. The Ravens also are one shutout shy of tying the 2000 defense's mark of four.

"When we go out there and play like Ravens, the sky is the limit," defensive tackle Brandon Williams said. "We dominate people."

What could hold back this stingy defense from being "super" is an offense that has struggled all season. Baltimore ranks 31st in offense and failed to score an offensive touchdown in the first half Sunday, the sixth time that's happened this season.

"Our defense is playing championship football," wide receiver Mike Wallace said. "Our offense, we have to catch up."

Skeptics will point out how two of the Ravens' shutouts came against backup quarterbacks. Baltimore blanked Miami's Matt Moore and Green Bay's Brett Hundley.

That also could mean the Ravens are gearing up for that fourth shutout Monday night, when they play host to the Houston Texans and backup quarterback Tom Savage.

Suggs has learned to take nothing for granted with this defense.

"We've had shutouts and then we've come back and not played so well," Suggs said. "We've got to build on that. The worst thing in the world is mediocrity. We don't want to be mediocre. We want to take the next step. We're taking next week like it's our Super Bowl."
