Here’s who played well and who didn’t for Dolphins on Monday: Grades, metrics, play time news

News and notes on every position, excluding quarterback, in the wake of the Dolphins’ 31-12 loss to Tennessee on Monday night at Hard Rock Stadium, a defeat that left Miami reeling at 1-3:

▪ Running back: De’Von Achane averaged just 1.5 yards per attempt (10 for 15). After averaging a league-best 7.8 yards last season, he’s 48th among running backs at 3.1 per carry this season.

PFF gave Miami poor run-blocking grades on Monday, but Achane deserves some of the blame, because his yards after initial contact have plummeted from last season.

Achane played 44 of the Dolphins’ 60 offensive snaps on Monday. Rookie running back Jaylen Wright played 28 and had nine carries for 32 yards (3.6 average).

Jeff Wilson Jr., who sustained a knee injury in pregame warmups, played two snaps and didn’t touch the ball.

▪ Wide receiver: Tyreek Hill and Jaylen Waddle have played two-plus seasons together. Their past three games represent their three least-productive games as teammates, in terms of total combined receiving yardage.

They combined for 59 receiving yards on Monday — their lowest as teammates — after mustering 64 and 65 as a tandem the previous two weeks.

Each had a dropped pass Monday, and Hill’s fumble on a backward “pass” earlier in the game was costly.

Hill played 44 snaps and Waddle 43. The Dolphins gave comparable snaps to the other three receivers who were active — practice squad player Dee Eskridge (17), Braxton Berrios (15) and rookie Malik Washington (14).

▪ Tight end: In a continuing trend, Julian Hill played the most snaps of the tight ends (30). Durham Smythe’s role continues to be reduced; he played 18 snaps.

Jonnu Smith played 25 snaps but was targeted only once all night; his lack of usage in the passing game has been puzzling. Smith also permitted two pressures on the three plays that he was asked to pass protect.

PFF rated Hill Miami’s second-worst player on offense Monday, ahead of only Berrios.

Tight end Tanner Conner played two snaps on offense.

▪ Offensive line: Pro Football Focus rated right guard Liam Eichenberg the Dolphins’ best player on offense on Monday night. Center Aaron Brewer was rated Miami’s fourth-worst player on Monday night and left guard Robert Jones was rated Miami’s third-worst player.

Left tackle Patrick Paul — making his first NFL start while Terron Armstead looks to clear concussion protocol — permitted three pressures and a sack. Every other starting offensive lineman except Brewer permitted two pressures.

PFF rated Brewer as Miami’s best pass protector against Tennessee, while Eichenberg was rated the Dolphins’ best run blocker.

Jones, Austin Jackson, Paul and Brewer received low grades for their run blocking — a big reason Miami averaged just 3.5 yards per carry.

▪ Defensive line: Zach Sieler played 51 of 65 defensive snaps, with De’Shawn Hand logging 37, Calais Campbell 36, Benito Jones 32 and Brandon Pili 11.

PFF rated Campbell the best of Miami’s defensive linemen on Monday — seventh of 20 who played defensive snaps.

Campbell had four quarterback pressures and Sieler three.

▪ Outside linebacker: Jaelan Phillips left for good in the third quarter with a knee injury after playing 32 of 65 defensive snaps. That created more work for Chop Robinson (22 snaps) and Quinton Bell (15), supplementing Emmanuel Ogbah (54 snaps).

PFF rated Bell the Dolphins’ second-best defensive player on Monday, behind only cornerback Jalen Ramsey. Ogbah was sixth, Phillips eighth and Robinson 16th of 20.

Robinson had one pressure on 13 pass rushing chances; he’s still looking for his first NFL sack. What’s more, Robinson was rated by far Miami’s worst run defender on Monday. PFF said Ramsey, Jevon Holland and Bell were the Dolphins’ top three run defenders.

▪ Inside linebacker: With David Long Jr. missing the game with a hamstring injury, Anthony Walker Jr. started and played 59 snaps opposite Jordyn Brooks, who had 13 tackles and played all 65 snaps.

Duke Riley also started in a three-inside linebacker package and played nine snaps.

PFF rated Brooks 11th and Walker 17th among all Dolphins defenders on Monday.

Pass coverage remains a problem for Miami’s inside linebackers, as it has for years. Brooks permitted five of six passes in his coverage area to be caught for 47 yards.

▪ Safety: Jordan Poyer dealt with a shin injury much of the game and left for good in the fourth quarter, after playing 37 snaps. He was replaced by Marcus Maye, who logged 30 defensive snaps.

Holland played 61 snaps and Elijah Campbell played 6.

Among Miami’s 20 defensive players on Monday, PFF rated Holland third, Maye fifth and Poyer 18th.

▪ Cornerback: With Kendall Fuller in concussion protocol, Storm Duck started on the boundary and played 60 of Miami’s 65 defensive snaps, with Ramsey playing 61.

Per PFF, Duck permitted three of four passes in his coverage area to be caught, for 23 yards.

Kader Kohou, who played 33 snaps, allowed two passes in three targets, but for just 9 yards.

The only pass thrown with Ramsey in coverage was incomplete.

Ethan Bonner played his first four defensive snaps of the season.
