ENGLEWOOD, Colo. -- When Denver Broncos cornerback Chris Harris Jr. said this season was "Super Bowl or bust" earlier this month, that was one thing.

After all, folks all over the region are thinking the same thing as they look over the Broncos' depth chart that still includes Peyton Manning at quarterback with a fairly young roster around him and one of the league's biggest hauls in free agency as well.

But now new arrival DeMarcus Ware has brought another goal into the conversation. Asked about the expectations of the team's defense, Ware said he hopes the Broncos go to uncharted ground when it comes to the franchise's history.

"We are trying to be a force to be reckoned with this year and you already talked about us being an offensive team, but at the end of the day, we are trying to be [No.] 1 and [No.] 1," Ware said. "The best offense in the league and the best defense in the league."

That's not just a lofty goal, but something the team has never done in five-plus decades worth of football business. The team has been to seven Super Bowls -- six of those on Pat Bowlen's watch -- and won two title games. But the Broncos have never finished a season with the No. 1 defense in yards allowed per game, which is what the NFL uses to statistically rank defenses each year.

The Broncos' best season in scoring defense -- when they allowed a franchise low 148 points in a 14-game season -- was 1977. They finished ninth in yards allowed and were third in scoring defense, behind the Los Angeles Rams and Atlanta Falcons. Former Broncos head coach Mike Shanahan routinely has said a team will almost certainly be in the Super Bowl conversation with a top-five offense to go with a top-five defense.

Then, Shanahan has said, it comes down to playing your best when the lights are brightest. But even that will be no small chore for these Broncos. Overall the Broncos have had only four seasons when they even finished in the league's top five in yards gained per game on offense and yards allowed per game on defense -- again that's how the league ranks them each year.

In those four seasons -- 1996, 1997, 2004 and 2012 -- the Broncos won the Super Bowl only to close out the 1997 season. They were upset in the playoffs, at home, to close out both 1996 and 2012 and were thumped by Manning in the wild-card game to close out 2004.

But Ware has again raised the issue many of the Broncos defensive players, most notably defensive tackle Terrance Knighton, have touched on throughout this offseason. That it's great Manning and the offense can pile up the touchdowns, but the Broncos want, and need, to be known for something on the other side of the ball.

If the team can't win the Super Bowl in a year that they scored more points in a season (606) than any team in history, then it's clear the Broncos need to bring a little something more than offensive pizzazz to the table.

But the difference in saying you want a top defense to go with the top offense and actually doing it is galactic in size. Especially in the salary cap era, when many teams find themselves picking sides when they're doling out the contract cash. And that was something John Elway was trying to avoid this past offseason when he was waving Bowlen's checkbook around in free agency, securing players such as Ware, cornerback Aqib Talib and safety T.J. Ward for the team's defense.

"I think that we've got to get to be where we're a complete football team," Elway said Wednesday. "We can't rely on [No.] 18 to win it because he can't win it by himself."

The 2013 season will always have its place in the team's lore as Manning threw for more touchdowns on his own (55) than the 31 other teams each scored. But the team never, whether it was because of injuries, mistakes or simply a lack of personnel, showed it had a Plan B for the days when the offense and Manning couldn't pull the team through -- like the day Super Bowl XLVIII was played, for example.

The Broncos didn't run the ball well enough not to have to throw it all the time and they didn't play defense consistently well enough to close the deal. Although the Broncos defense may have actually had one of its better days against the Seahawks in February until things got out of hand.

"To win a world championship, you have to be a great football team and you have to be well rounded," Elway said. "I think we've moved closer to that. Seattle was a tremendous football team. But this is a new year and we've got to go out and we've got to play the best football that we can play, and do what we do best. And how the coordinators put our guys in the best situations to be successful and we'll create our own identity. I think if we continue to do that with the people that we have, we're going to be able to compete for a world championship."

"I think this is going to be a night and day defense from last year," Ware said. "You had guys that were hurt [last year], and have the opportunity to not have any holes in your defense … So I think the sky is the limit for us."
