PITTSBURGH — The Miami Dolphins had their four-game winning streak snapped and were eliminated from playoff contention in Monday night’s loss to the Pittsburgh Steelers.

Miami appeared to handle the cold in Acrisure Stadium well in the first half, but then forgot how to tackle in the second half, allowing the Steelers to get rolling.

The offense was not moving as the Dolphins failed to sustain drives and didn’t even have 100 yards of offense until early in the fourth quarter, when they scored a couple of touchdowns with the score out of reach.

Here are Dolphins’ grades from their 28-15 loss to the Steelers:

Run game: C

De’Von Achane had 60 yards on his 12 carries as he battled his rib injury. He wasn’t the problem, averaging 5 yards per carry. But the Dolphins couldn’t get anything meaningful going on the ground during a critical juncture when the Steelers scored touchdowns on four consecutive drives from the end of the first half to the start of the fourth quarter. In the third period, Miami went three-and-out twice, with runs going nowhere to start those drives and put the team in difficult second and third downs.

Pass game: D

The stat line will say one thing, with quarterback Tua Tagovailoa finishing 22 of 28 for 254 yards and two touchdowns to tight end Darren Waller, but virtually all of the good there was collected once the score was out of reach, at 28-3 in the fourth quarter. The Dolphins couldn’t keep their offense on the field, at 2 for 8 on third downs. Tagovailoa threw a bad early interception, not recognizing the depth cornerback Asante Samuel Jr. had underthrowing Jaylen Waddle on a corner route. He took four sacks, and some of those were vital third-down failures as Pittsburgh pulled away.

Run defense: C-

Kenneth Gainwell had success on the ground with 80 yards on his 13 carries. The Steelers averaged 4.2 yards per rush. Some tackling woes surfaced with the way Miami came out for the start of the second half after the team had the right mindset to tackle in the cold in the first half. The Dolphins allowed fullback Connor Heyward to convert 3 of 4 Tush Push attempts, including one for a touchdown at the 1-yard line. And Miami allowed former Dolphins tight end Jonnu Smith to score on a rushing touchdown. Can’t allow him to have that moment on your team to go up 28-3 after trading him in the offseason.

Pass defense: D

Steelers quarterback Aaron Rodgers was 23-of-27 for 224 yards and two touchdowns. It was a lot of Gainwell in the flat until the game opened up a little for the Pittsburgh offense. Then he found Marquez Valdes-Scantling for an open touchdown on a breakdown in coverage. DK Metcalf scored his after safety Ashtyn Davis failed on his gamble attempt at an interception, and Metcalf shoved Minkah Fitzpatrick aside in Fitzpatrick’s return to Pittsburgh after spending six seasons there. The Dolphins did get after Rodgers with three sacks, by Jordyn Brooks, Zach Sieler and Zeek Biggers.

Special teams: C

Kicker Riley Patterson had an impressive 54-yard field goal kicking into the open end zone to barely sneak it over the crossbar. Jake Bailey had some punts booming later in the game, but also had a touchback punting from the 50-yard line and another punt that only traveled 36 yards that didn’t get to the opposing 20-yard line. Some miscues surfaced between Patterson’s kickoff short of the landing zone, which started the Steelers at the 40-yard line on their first touchdown drive, and a delay of game in punt formation.

Coaching: D

I like the move of practicing Saturday night in the elements of Pittsburgh in preparation for the Monday night game. That showed in the first half, as the Dolphins were playing physical in the cold and tackling well. Something changed in the second half, and it warrants criticism on coaching for not getting players to maintain that same mindset. Coach Mike McDaniel was heavily criticized by Troy Aikman on the ESPN broadcast for not showing more urgency and hurrying on the late fourth-quarter drives. McDaniel said he was merely focused on getting the ball in the end zone, regardless of the time it took, figuring an onside kick would have to be part of the comeback equation, anyway.

Stock up: Darren Waller

Just throw the ball up to him! He showed that when he took advantage of a mismatch for his first touchdown. Waller caught two in the late stages, and it has you wonder what could be if he stays involved in the offense instead of having these moments when McDaniel and Tagovailoa get away from him. Waller now has four touchdowns in two Monday night games this season.

Stock down: Nick Westbrook-Ikhine

How has he been such a no-show all season after scoring nine touchdowns with the Tennessee Titans last year? Especially in a Dolphins receiving corps that needed someone to step up behind Jaylen Waddle after Tyreek Hill went down. No catches on Monday, and he was targeted once. He was bound to be the read on one play where he fell down and thought he was injured. On the season, Westbrook-Ikhine has 11 receptions for 89 yards and is without a touchdown.
