Dolphins vs. Cowboys: Who has the edge?

Here’s a look at how the Miami Dolphins (10-4) and Dallas Cowboys (10-4) match up in six key areas ahead of Sunday’s Week 16 game at Hard Rock Stadium (4;25 p.m., Fox):

When the Dolphins run: The Miami run game is down to No. 4 in the NFL, from 2, after collecting just 77 rushing yards in last Sunday’s 30-0 win over the New York Jets, but the Dolphins did something more valuable than any yardage total. They punched it in on the ground when down near the goal line. On Raheem Mostert’s first score, it was his third consecutive try from either the 1- or 2-yard line. He got in again later for his 20th touchdown on the season, a franchise record.

Mostert and rookie De’Von Achane are together again as the speedy 1-2 punch. The offensive line in front of them is hampered by injury, though. Right tackle Austin Jackson exited the Jets game with his pestering oblique injury. Center Liam Eichenberg, the backup for Connor Williams, who was lost for the season, played through a calf ailment. Left tackle Terron Armstead is battling ankle and knee injuries. Right guard Robert Hunt has missed five of his past six starts with an ailing hamstring.

That banged-up offensive line will face a talented Cowboys defensive front, but one that is vulnerable on the ground, 19th in the league in run defense. Big nose tackle Johnathan Hankins was also missing practice early in the week. Young middle linebacker Damone Clark leads the team with 94 tackles, and linebacker Leighton Vander Esch is on injured reserve. Edge: Dolphins

When the Cowboys run: As Tony Pollard has taken over the Dallas backfield from longtime running back Ezekiel Elliott, he has been decent but nothing very special. Pollard is averaging 4.1 yards per carry, 848 yards on 207 attempts, for five touchdowns. The Cowboys run game, overall, is ranked 12th in the league.

The Dolphins have the No. 4 rushing defense in the NFL, anchored by defensive tackles Christian Wilkins and Zach Sieler up front. And since Week 5, Miami’s run defense is second in the league. Dallas’ elite six-time All-Pro right guard Zack Martin is also dealing with a thigh injury. While the Dolphins are without Jerome Baker, fellow linebacker David Long Jr. has been elite against the run and Duke Riley has come in to make the calls on the defense that Baker used to communicate to the unit. Edge: Dolphins

When the Dolphins pass: Quarterback Tua Tagovailoa operated the offense well against the Jets while star wide receiver Tyreek Hill sat with his bad ankle, quieting some of the skeptics that attribute his success to Hill’s presence. He hit the deep touchdown to fellow wideout Jaylen Waddle, who stepped up for his best game of the season with eight receptions for 142 yards. Tagovailoa was 21 of 24 without turning the ball over.

If Hill can return to the lineup Sunday, he and Waddle will face a Cowboys secondary that lost ballhawking cornerback Trevon Diggs two weeks into the season, but in his place, Dallas has DaRon Bland with eight interceptions, five of them returned for touchdown. Former All-Pro Stephon Gilmore is opposite him for the league’s No. 4 pass defense.
