Joyner breaks down how Eagles will prepare for 49ers offense

Jimmy Garoppolo Elijah Mitchell

It was a tale of two halves for the Philadelphia Eagles defense in Week 1. The Atlanta Falcons gashed the Eagles for 110 yards on the ground in the first half, before buckling down and surrendering just 14 in the second half.

Especially as they prepare for Kyle Shanahan's offensive attack, which is built on an effective ground game, the Eagles know they can't afford to struggle out of the gate against the run.

"They're gonna look at the first half of that Atlanta game and believe that they can run the ball at will on this Philadelphia Eagles defense," NBC Sports Philadelphia analyst Seth Joyner said.

Joyner, a three-time Pro Bowl selection and Super Bowl champion, goes on to explain why Philly must force the 49ers to rely on Jimmy Garoppolo's (and possibly Trey Lance's) arm to move the ball.

The 49ers did run for 131 yards in the 41-33 Week 1 win over the Detroit Lions, the 11th-best total among NFL teams. Trey Sermon was a surprise healthy inactive, but rookie Elijah Mitchell dashed for 104 yards and a touchdown after Raheem Mostert went down with what ended up being a season-ending knee injury.
