Here’s a look at how the Miami Dolphins (6-7) and Pittsburgh Steelers (7-6) match up in six key areas ahead of Monday night’s Week 15 game at Acrisure Stadium (8:15 p.m., ESPN):

When the Dolphins run: Miami’s speedy 1,000-yard rusher, De’Von Achane, sustained a rib injury last Sunday, but he has a positive outlook toward playing after an X-ray and MRI came back clean. Even after he and his 92 rushing yards exited in the win against the New York Jets, second-year tailback Jaylen Wright had a career afternoon with his first 100-yard rushing game and first NFL touchdown. Between the two and rookie Ollie Gordon II, all three found the end zone and the team totaled 239 yards rushing.

It’s a testament to the way the Dolphins are blocking up front. Not only is it the offensive line, but Daniel Brunskill in jumbo sets as an extra lineman and tight ends Julian Hill and Greg Dulcich, along with fullback Alec Ingold after he’s been inconsistent much of the season. All the blocking, plus coach Mike McDaniel’s scheming up the run game, has Miami at No. 8 in rushing offense.

The ground attack goes against a Steelers defensive front that ranks No. 21 against the run. Pittsburgh gave up 249 rushing yards against the Buffalo Bills two weeks ago and 217 against Baltimore Ravens last week. The Steelers certainly have the names to turn it around in a blink, between veteran defensive tackle Cameron Heyward and linebacker Patrick Queen, but a big factor could be if they have rookie defensive lineman Derrick Harmon available Monday. Edge: Dolphins

When the Steelers run: There’s not much to stopping the Pittsburgh run game. It’s certainly not a feared group with Jaylen Warren and Kenneth Gainwell combining for the No. 29 rushing offense in the league. The Steelers can get some things done on the ground here and there behind center Zach Frazier and guard Isaac Seumalo.

The Dolphins rank 25th overall against the run, but they have been stout since Week 8, ranking seventh in the league in that span at 100 rushing yards allowed per game. Miami is coming off holding the Jets to 65 yards rushing and under 4 yards per carry. Linebacker Jordyn Brooks brings his league-leading 142 tackles into Monday night. Rookie defensive tackle Zeek Biggers’ increase in snaps in recent weeks has helped the defensive line against the run. Edge: Dolphins

When the Dolphins pass: Quarterback Tua Tagovailoa has failed to reach 175 passing yards in four consecutive games. He had his first touchdown pass in three games when he found wide receiver Jaylen Waddle in the end zone. He also nearly threw multiple interceptions against the Jets, who still don’t have one all season. But this is the Dolphins offense later in the season, with star wide receiver Tyreek Hill out for the season and the run game spearheading the charge.

Miami faces former cornerback Jalen Ramsey, who is now playing safety in Pittsburgh, due in part to the knee injury to former Dolphins safety DeShon Elliott. At cornerback, the Steelers have young Joey Porter Jr., former Deerfield Beach High and FAU standout James Pierre, and Brandin Echols, who has two interceptions in his career against Tagovailoa, in the nickel. That secondary will look to contain Waddle, keep big tight end Darren Waller from surging and will also have to account for Dulcich after he actually led Miami in receiving last week.

The Dolphins’ No. 28 pass game goes against the Steelers’ No. 28 pass defense. But Pittsburgh, with 36 sacks this season, is capable of applying pressure. T.J. Watt,  Alex Highsmith and Nick Herbig are fierce on the edge, and Heyward can bring it from the interior, along with fellow defensive tackle Keeanu Benton. Edge: Steelers

When the Steelers pass: The Dolphins struggled against quarterback Aaron Rodgers each of the two times they faced him with the Jets last season. In Pittsburgh this season at 42 years old, he is completing 65.4 percent of passes for 2,370 yards, 20 touchdowns and seven interceptions.

As he’s in his first season with the Steelers, his top target is former Seattle Seahawks wide receiver D.K. Metcalf, who has 52 receptions for 753 yards and five touchdowns. His big body on the outside always creates tough matchups for cornerbacks, but reigning AFC Defensive Player of the Week, cornerback Rasul Douglas, could possess the size and length to match up. Douglas has an interception in back-to-back games and had a whopping five passes defensed against New York. It’s also Minkah Fitzpatrick’s return to Pittsburgh as he has been mixing in snaps at the nickel since coming back to the Dolphins. The Miami secondary will have to handle a three-headed monster at tight end: Pat Freiermuth, big Darnell Washington and former Dolphin Jonnu Smith.

Miami, since Week 10 (four games), is No. 1 in scoring defense (13.3 ppg allowed), No. 1 in red-zone defense (22.2 percent) and third in third-down defense (30.8 percent). The pass rush is also starting to catch fire after a six-sack effort against the Jets, led by 2 1/2 from defensive tackle Zach Sieler. Chop Robinson had a strip-sack last Sunday, as he has gotten going to complement Bradley Chubb’s team-leading 6 1/2 sacks opposite him. The Steelers have had to shuffle through left tackles. Whoever starts there and young right tackle Troy Fautanu will have their hands full. Edge: Dolphins

Special teams: The Dolphins have been solid on special teams all season, but they’re coming off blunders in back-to-back games. After they allowed the onside kick to be recovered against the New Orleans Saints two games ago, they had multiple miscues against the Jets between the punt return touchdown surrendered and a first down allowed on a fake.

Dolphins kicker Riley Patterson and the Steelers’ Chris Boswell have each missed three kicks this season. Pittsburgh punter Corliss Waitman (42.1) and Miami’s Jake Bailey (43.3) are comparable in net punting. The Dolphins have a better return game, but the recent mishaps have this matchup square. Edge: Even

Intangibles: The Dolphins are on a four-game winning streak, have developed excellent camaraderie down the stretch and are fighting for their playoff lives every week. Pittsburgh, which has been uneven since its 4-1 start, did just earn a big division win to get back in front in the AFC North.

Temperatures should be in the teens in western Pennsylvania on Monday night. Miami did get a little bit of a warmup to the cold, with temperatures in the high 30s in the Meadowlands last Sunday. This is different, though, and the Dolphins are 4-12 in night games under McDaniel. Don’t discount Miami’s new identity of physicality at the line and effectiveness in sticking with the run game as potentially helping the team in those conditions. Edge: Steelers
