The Eagles have a chance to go into their bye week with an 8-1 record and seven straight wins.
The Broncos stand in their way.
No, Denver (3-4) hasn't been the team folks in Colorado were probably hoping to see this season. After winning three of their first four, the Broncos are losers of their last three games, including a loss to the Chiefs on Monday night.
And now they've decided to switch quarterbacks on a short week.
While the Broncos' offense has looked inept at times this season, that defense is no joke and can keep them in any game.
Here's a look at five matchups the Eagles need to win Sunday:
Lane Johnson and 'Big V' vs. Von Miller
This matchup — along with ones against Demarcus Lawrence and Khalil Mack — is one of the reasons the Eagles decided to keep Johnson at right tackle instead of flipping him to left.
Miller is the best pass rusher the Eagles will face all season or ever. This season, Miller already has seven sacks in seven games. And since he entered the NFL in 2011, he leads the league in sacks with 80½. He's an absolute game-wrecker.
Now, you're probably wondering why Miller wouldn't just move to the right side of the defensive line and go against Halapoulivaati Vaitai. He probably will, at least some on Sunday. But it's pretty clear Miller is more comfortable on the defensive left, so the Eagles are forcing him to switch sides.
Menelik Watson vs. Brandon Graham
On the flip side, there's a reason many top edge rushers line up on the right tackle. Watson is a perfect example. He's just really struggled this season and Graham has a chance to absolutely feast on Sunday.
Watson, according to ProFootballFocus, has given up an NFL-high eight sacks to go along with 12 QB hurries and three quarterback hits.
On the other side, the Broncos use rookie Garett Bolles, who has been a little better but still looks like a rookie even though he's 25. Bolles has given up three sacks and will have to deal with a resurgent Vinny Curry and an improving Derek Barnett.
Eagles' run game vs. Broncos' run D
Nose tackle Domata Peko has made a huge difference for the Broncos, who are really stout against the run this season. They've given up just 72.9 yards per game, second best in the league after the Eagles.
What's even more impressive is what the Broncos have done against some of the better runners the NFL has to offer. Melvin Gordon had 54 yards and 38 yards in his two meetings against the Broncos, Ezekiel Elliott had eight, LeSean McCoy had 21, Marshawn Lynch had 12, Kareem Hunt had 46.
The Eagles added Jay Ajayi this week but it's unclear just how big of a role he'll have in his first game. LeGarrette Blount has been performing well so far this season, too, and the Eagles are the fifth-best rushing team in the NFL. But whoever runs the balls is going to have their work cut out for them.
Broncos' run game vs. Eagles' run D
The flip side of that is the Eagles have the best run defense in the league, giving up just 70.4 yards per game on the ground this season. Meanwhile, the Broncos have been the NFL's 10th-best rush offense.
The Broncos use a few different backs. C.J. Anderson is still the guy who gets the most work, but Jamaal Charles and Devontae Booker get worked in, too. Charles and Booker might be bigger concerns as receivers out of the backfield.
Brock Osweiler vs. Jim Schwartz
Broncos head coach Vance Joseph is making a quarterback switch for his team this weekend. Trevor Siemian is out and Osweiler is in.
Osweiler found some success with the Broncos a few years ago but then went to the Texans on a $72 million deal and was traded to the Browns for absolutely nothing. The Browns cut him six months later and he returned to the Broncos as a backup.
Now, he's the starter again.
It would make some sense if Schwartz tried to knock the rust off Osweiler himself by blitzing a lot on Sunday, but he probably won't need to. The Eagles ought to be able to get plenty of pass rush against the Broncos with their front four alone. It'll be a tough test for Osweiler but it's hard to imagine the Broncos' offense looking any worse than it did on Monday night against the Chiefs.
