ENGLEWOOD, Colo. -- The members of the Denver Broncos defense are quick to remember their recent history because they would very much like to repeat it.

They remember closing out the regular season and then powering the Broncos through a postseason run when the defense faced Ben Roethlisberger, Tom Brady and Cam Newton. During that run they had 14 sacks, three interceptions and held three of the league's top four scoring offenses to 16, 18 and 10 points.

The Broncos might need the same, and more, to earn their way into the postseason party this time around.

"This year, we've been every team's Super Bowl," cornerback Chris Harris Jr. said. "We've had some guys get injured, had some things we needed to tighten up and all that. But we feel like we want to be the best defense on the field every week and that we can do that and if we do that we can be there at the end."

No team in the league has a more difficult finishing stretch, as the Broncos' four remaining opponents have a combined winning percentage of .729.

The Broncos face the Titans (6-6) Sunday and then New England (10-2), Kansas City (9-3) and Oakland (10-2). Oakland and Kansas City have each already defeated the Broncos this year.

"They're all big right now," outside linebacker DeMarcus Ware said. "This time of year, if you want to be in the playoffs, you have to do what you need to do to get there."

This time around for the Broncos defense -- which finished 2015 at, or near, the top of the league rankings in all of the major defensive categories -- some on-the-fly repairs will have to be made as offenses have found plenty of room to run the ball.

And the Titans, as the league's No. 3 rushing attack averaging 141.5 yards per game, may provide the Broncos with one of the more difficult matchups they could have drawn at this point in the season. The Titans have two power backs in Derrick Henry and DeMarco Murray and have invested premium draft picks in the offensive line with first-round picks at both tackle spots in Jack Conklin and Taylor Lewan.

"They have a ton of formations," Kubiak said. "They're a big football team. They have two first round picks at tackle. They have two backs, that not only are good backs, but are big backs. This team is capable of pounding you. We've had some issues with the run, so we know we're going to get tested."

Several personnel executives around the league have said this season, after seeing the Broncos defense play, the team may miss linebacker Danny Trevathan the most of those players who departed this past offseason.

Brandon Marshall, having switched over to Trevathan's spot at inside linebacker, has not reached the level of performance he had last season alongside Trevathan -- Marshall recently called his season "very average" thus far. The Titans have rushed for at least 149 yards in five of their games and have topped 200 yards rushing twice. Murray is second in the league in rushing -- 1,043 yards after 12 games -- while Henry has averaged 4.5 yards per carry.

"For two big guys, they make a lot of big plays," Kubiak said. "They do cut backs and take the ball across the field. They also have a quarterback that can run. They've been moving the ball extremely well. They're tough to deal with."

But with three turnovers that all meant something in this past Sunday's win Jacksonville, the Broncos believe there is more to come. Harris stopped a Jacksonville drive when he intercepted a pass on the Broncos' 13-yard line and cornerback Bradley Roby returned an interception for a touchdown.

And Von Miller forced a fumble late in the game with is rush on Jaguars quarterback Blake Bortles and the resulting sack made it 12.5 for him this season.

"The no-fly zone, when they make plays like that it gets us over the top," Ware said. " ... They are aggressive players back there and they play hard and when they're doing what they did, we can be at our best, against Tennessee and then right on down the line to close out the season."
