Not much of anything went right for the Miami Dolphins on Thursday night.

In a pivotal divisional game that served as an opportunity to announce to the AFC East that the Buffalo Bills are kings no longer, the Dolphins did the opposite. Miami was dominated in just about every aspect, turning the ball over to the Bills seven times when four turnovers on downs are included.

A brutal night for the Dolphins got even worse in the third quarter when quarterback Tua Tagovailoa's night ended with a scary concussion suffered on a scramble up the middle of the field. After colliding headfirst with Bills safety Damar Hamlin, Tagovailoa exited to the locker room where he remained for the rest of the game.

On top of that injury, the Dolphins also lost starting offensive linemen Terron Armstead and Robert Jones to shoulder injuries and running back Jeff Wilson Jr. to an oblique strain.

Here's who struggled most Thursday and the few who shined in the disastrous loss:

Stud: RB De'Von Achane

Let's start with the positive: De'Von Achane is still that dude.

Despite entering the night questionable with an ankle injury, Achane was easily the Dolphins' best player in the loss with 96 rushing yards and 69 receiving yards -- both of which led both teams.

During his electric rookie year, Achane usually played the change-of-pace role in the Dolphins backfield with Raheem Mostert getting the majority of the carries and the newcomer serving as the occasional curveball. On Thursday, Achane showed he's plenty capable of being a bell cow, if necessary. His 29 total touches were a career-high and Achane wasn't afraid to batter his way to yards between the tackles.

Dud: WR3

The Dolphins' utter lack of a reliable third wide receiver was never more glaring than Thursday night.

Tua Tagovailoa's first interception of the night bounced directly off the shoulder pad of Grant DuBose and his second sailed over the head of Robbie Chosen. It was tough to immediately tell how much at fault Tagovailoa was on the passes, but it wasn't hard to see that neither were on the same page with the quarterback.

What is clear, and has been clear, is that the Dolphins are severely lacking a solid third option at receiver after Tyreek Hill and Jaylen Waddle. That proved costly Thursday.

Dud: QB Tua Tagovailoa

There's significant concern for Tagovailoa after he suffered a concussion Friday night that appeared very serious. And if the quarterback is out for any amount of time, it's a huge blow for a Dolphins offense that was among the best in the NFL last season with Tagovailoa at the reins.

But none of that changes the fact that Thursday was a rough outing for the quarterback. While an argument could be made that the first two interceptions weren't entirely on Tagovailoa, his third of the night was an inexplicable mistake that all but erased any hope of a Dolphins comeback.

Add in the lack of urgency on their drive before halftime and it was a poor showing from Tagovailoa through and through.

Dud: Mike McDaniel's clock management

No, but seriously -- what was up with that last drive of the first half?

With more than three minutes left in the second quarter and all three timeouts, it seemed the Dolphins had all the tools necessary to try to cut the Bills' 24-7 lead to 10 points before halftime. Instead, they were so casual about their drive that they settled for a field goal on a third down on the outskirts of the red zone.

Three points was far from the worst result possible for that drive, but it sure would've been a good idea for the Dolphins to at least take some shots at the end zone or exhaust their downs before settling.

Dud: S Jordan Poyer

In Poyer's first game against his former team, the veteran safety didn't exactly make the Bills regret cutting him earlier this year. If anything, he gave them every reason to believe they did the right thing.

Poyer struggled in coverage, took a poor angle that sprung James Cook loose for a 49-yard touchdown run, and picked up a 15-yard penalty for a helmet-to-helmet hit on Khalil Shakir.

Buffalo saved $5.7 million by cutting Poyer in March, but on Thursday night, they looked better off with Damar Hamlin, regardless of the price.

Dud: Dolphins pass rush

Chop Robinson showed some flashes and a couple blitzers forced Josh Allen to roll towards the sideline, but that was about it on a zero-sack night for the Dolphins defense. After getting a sack in his first game back from an Achilles injury, Jaelan Phillips only played 23 snaps and made hardly any impact. Veterans Emmanuel Ogbah and Quinton Bell didn't do much of anything either.

Stud: Throwback jerseys

The Dolphins looked good, at least.
