QUARTERBACK

Consider this a step in the wrong direction. Ryan Tannehill had not thrown ill-advised passes or into double-coverage before this game. Yes, he had passes batted and those were intercepted against Houston. But this game had Tannehill’s throws sailing straight into the wrong hands — three times. One interception was returned for a touchdown and the third required a Tannehill tackle to prevent another TD. The strange thing is the Titans have been willing to allow big days this season but Tannehill found no rhythm or consistency. The rookie played like a rookie on a bad day. GRADE: F.

RUNNING BACKS

Reggie Bush fumbled and was taken out of the game — rightly in his own opinion. Daniel Thomas and Lamar Miller were used to relieve Bush but failed to provide any sort of spark against one the NFL’s worst run defenses. Thomas was active in the passing game, catching five passes for 34 yards. That’s good news for Thomas but when a running back is among the team’s top receivers, that’s not good news for the team. GRADE: C-minus.

RECEIVERS/TIGHT ENDS

Davone Bess dropped a pass but was otherwise open most of the day. He successfully picked up a pass interference call against the Titans. Brian Hartline failed to get separation on a shot into the end zone but otherwise caught practically everything thrown his direction. Hartline was not able to get behind the Titans secondary, however. The Dolphins still do not get any consistent contribution out of their tight ends. Anthony Fasano was invisible in the passing game, catching one pass for 4 yards. Charles Clay had one inconsequential catch as well. GRADE: C.

OFFENSIVE LINE

It was this group’s worst outing of the year. Forget that Richie Incognito helped kill a drive with a 15-yard personal foul. Forget that Mike Pouncey and Jake Long had holding calls, although the one against Long was declined. Forget that Incognito gave up a sack and the entire right side gave up multiple hurries. The problem is the Titans have been horrible against the run this year and the Dolphins could not establish a running game early in the game. That was the biggest failure of the day. GRADE: F.

DEFENSIVE LINE

Chris Johnson became the first running back in the past 22 games to break the 100-yard barrier against the Dolphins. He did much of his damage by running through huge gaps on cutbacks that suggested the Dolphins didn’t do a good job with their gap discipline. They also didn’t do a very good job applying pressure on Jake Locker. Yes, they got one sack, but that came from Jimmy Wilson on a quarterback blitz. GRADE: D.

LINEBACKERS

Koa Misi had a tackle for loss early in the game. That’s it. That was the extent of the best work by Miami’s linebackers. They got caught in the wash of Chris Johnson’s cutback runs. They struggled to break free from blockers on the second level. It was not a good day. GRADE: D

SECONDARY

Jimmy Wilson and Sean Smith struggled for the second consecutive week. Wilson gave up a TD on a short slant. Chris Clemons, meanwhile, did not provide inside help on that pass. Reshad Jones gave up a 26-yard TD. Smith is giving receivers too much cushion and they’re simply taking quick out or comeback patterns for multiple first downs. And that moment when Locker threw up a prayer and the receiver, so uncovered he was lonely, simply camped under it for a reception, was obviously a broken coverage. GRADE: D.

SPECIAL TEAMS

The Dolphins had three block-in-the-back penalties on special teams. How hard is it to not block someone if you see his back? Marlon Moore also ran into the punter and there was also an unacceptable 27-yard punt return by the Titans. This group had been at the forefront of the Dolphins’ rise the past month. Not this game. GRADE: B.

COACHING

The Dolphins failed to start fast on offense and seemed flat-footed on defense. The decision to ice Reggie Bush between the first and second quarter — not coincidentally after he fumbled — was curious when compared to the fact quarterback Ryan Tannehill, who threw three interceptions, didn’t get benched until the game was decided. GRADE: F.

OVERALL

This is probably the first game of the season the Dolphins lost when they should have won. They not only got beat, but trounced by an inferior team. GRADE: F.
