The Eagles are back home and it seems like they are finally comfortable.

Comfortable in the standings (just a half game behind the Giants, who face New England this week), comfortable in Chip Kelly's offense, and comfortable with their roles on the team.

Without truly dominating but with flickers of what might be (if everything worked perfectly), the Eagles have a workable defense -- boasting the most takeaways in football -- and an offense that can do some real damage once it gains a first down or two.

The Dolphins (3-5) are next on the docket, a team that is struggling under a new head coach and with some underachieving players.

Here are three keys to the Eagles' success Sunday afternoon at the Linc:

Stopping potent Ryan

The Eagles (4-4) have another mobile quarterback to oppose in Ryan Tannehill Sunday, a player so athletic that Kelly recalls him lining up at wide receiver as a college underclassmen just so he could get on the field.

"He's a dual threat," Kelly said. "I think it's a little bit different than facing an Eli [Manning]. Obviously, Eli is so talented throwing the football, but you're focused on that part of him. You're not worried about Eli taking it, tucking it, and running on you; with [Tannehill], you have to."

Eagles fans will recall the damage another similar QB, Panthers Cam Newton, did with his legs in the Eagles' Week 7 loss.

"They actually have designed quarterback runs similar to playing Carolina with [Newton]. It's more like going in against a Cam than it is going against an Eli."

Don't stop running

The Eagles have had a turnaround in the run game lately, and according to DeMarco Murray, it's a product of hard work and repetition.

“I think it’s the everyday, every week deal,” Murray said. “You get more and more comfortable the more you run plays. Me and Ryan [Mathews] are new to the offense. We haven’t ran these plays in four or five years. I think it’s a process.”

The Eagles rank fifth in the NFL with just over 121 rushing yards per game this season. But if you narrow the scope to the last three games, Philly is second best with 169 yards per game.

Take it away now

Philadelphia leads all NFL teams with 2.5 takeaways per game. Miami averages just one per game and has generated just one during its last three contests.

If the Eagles can continue to win the turnover battle, it will go a long way toward continuing their winning ways. 

"All you can do is just harp on technique," Eagles defensive coordinator Bill Davis said. "If you're playing the technique and then when you're at the ball, play the ball and go for the ball. That’s part of the reason we're getting turnovers."
