The Eagles are one of the hottest teams in the National Football League, riding high off four straight victories, while the Detroit Lions haven't put together a winning (or losing) streak longer than two games this season.
This week's game is a huge swing in the NFC postseason race. The following slides will predict what happens in the game.
Nothing has stopped Nick Foles this season. He's tossed 19 touchdowns without an interception, and his passer rating would set a new single-season mark.
Why would that change against the Detroit Lions, who rank 26th in passing yards and 22nd in net yards per attempt?
Look for Foles to spread the ball around to DeSean Jackson, Riley Cooper and his tight ends. It's possible that he throws for 400 yards and four touchdowns. But he's due to throw his first interception.
Foles and the Eagles haven't played in a true shootout yet this season. That could easily change this week.
Matthew Stafford is a yardage machine. He topped 5,000 yards in 2011 and came within one throw of doing the same in 2012. Don't look now, but he's on pace for more than 5,000 yards again this season.
The Eagles have a bend-but-don't-break defense. They surrender tons of passing yards. Stafford fits the mold of a quarterback who could throw for 450 yards against them. And if he does that and throws 'only' three touchdowns, the Eagles will consider themselves lucky.
Expect Calvin Johnson to have a field day too, especially against Cary Williams.
Chip Kelly has made some interesting in-game decisions this year. Some of which have been good and led to victories. Some have been bad and cost the Eagles wins.
With Sunday's game a must-win for the Eagles, look for Kelly to make a bold decision or two... like a surprise onside kick.
Personally, I'd rather have Detroit's kicker for an onside kick (yes, that would be David Akers) than Alex Henery.
The Eagles' second-round draft pick from 2012 is finally getting a chance to make an impact on the field. Defensive end Vinny Curry has collected four sacks this season, which ranks second on the team.
He's not going to earn a starting job anytime soon, considering how well Fletcher Cox and Cedric Thornton have been playing, but he's a major upgrade over Thornton on passing downs.
Look for Curry to have a big game. Three sacks would give him a team-leading seven for the season.
The Philadelphia Eagles should beat the Detroit Lions on Sunday, which would give them a much higher chance of making the postseason, whether it's as a division winner or through the Wild Card.
It's not going to be a low-scoring game. Although the Eagles have allowed 21 or fewer points in eight straight games, Calvin Johnson might score three touchdowns alone on Sunday.
But Foles and the rest of the Eagles offense have been unstoppable lately. Playing at home with a playoff spot on the line should help.
This team is one game closer to the playoffs with an 8-5 record. For Detroit, the road to the postseason will get just a little bit tougher.
