The defending Super Bowl champion Denver Broncos (4-2) have suddenly dropped two straight games since their 4-0 start, but a Monday Night Football contest at home in Week 7 may curse their ills when the Houston Texans (3-3) come to town for a matchup that figures to be all about defense.

Denver rode their strong defensive unit to a title last season, capped off by an impressive 24-10 victory over the Carolina Panthers in Super Bowl 50 in which they pretty much manhandled one of the league’s best offenses. However, in their upcoming tilt, they’ll be taking on a club that is similarly built, as Houston boasts one of the AFC’s better defenses, while sporting a pretty good offense that features some big-time players. And of course, the top storyline in this one will be Denver taking on their former quarterback Brock Osweiler, who had a big role in last year’s championship triumph.

That’s just some of the reasons why Houston Texans vs. Denver Broncos tickets are currently trending high on the secondary market, being one of the most expensive games for Week 7. In fact, according to Razorgator, tickets to see the Texans and Broncos go at it are averaging $368.47, while the get-in price is as high as $144. Unsurprisingly, in Osweiler’s return to Denver, it’s one of the priciest games of the season for both clubs. Fans can at least save some money on their Sports Authority Field at Mile High parking by electing to go through ParkWhiz.com, which has numerous cheap parking options all around the stadium.

This contest will be the second straight primetime affair for both teams. In Week 6, Denver dropped a tough 21-13 decision to the San Diego Chargers on Thursday Night Football. Playing without head coach Gary Kubiak, Denver was unable to generate any offense against a resurgent San Diego front-seven. Houston, on the other hand, had a big showing on offense on Sunday Night Football against the Indianapolis Colts, pulling off a thrilling comeback victory that they would ultimately finish off in overtime. The likes of Osweiler, Lamar Miller and DeAndre Hopkins will be seeking to continue that momentum in this anticipated encounter.

These two teams have only played five times -- and Denver holds a slight 3-2 series lead. This will be their first meeting since 2013, though, when Denver won 37-13 at Reliant Stadium in Houston. Peyton Manning threw for 400 yards and four touchdowns in the victory, while Matt Schaub only threw for 176 yards and two interceptions. Of course, both of those quarterbacks are gone from their respective franchises, so there will be a completely different feel to this matchup.

Above all, the Broncos will be hoping their new quarterback, Trevor Siemian, can get back on track following a bit of a lackluster outing versus the Chargers. In his defense, it was his first game back from injury, and he might have been playing at less than 100 percent, so he’ll be leaning on the likes of Demaryius Thomas, Emmanuel Sanders and CJ Anderson to return to form. It won’t be easy though, as even without superstar JJ Watt, the Texans still boast one of the stronger defenses in the league. And in a showdown like this one, it will probably be defense that dictates how it all plays out.
