NASHVILLE, Tenn. – Doug Marrone wouldn't say he was "shocked" by the run defense, necessarily.

But the Jaguars' head coach is a realist – and he did say late Sunday afternoon that allowing 200 yards a game rushing will get you … 

Well, it will get you what it has gotten the Jaguars in recent weeks.

"It's disappointing, and it's very difficult to win in this league – obviously – if you can't stop the run," Marrone said following a 42-20 loss to the Tennessee Titans at Nissan Stadium Sunday.

Titans running back Derrick Henry rushed for 159 yards and two touchdowns on 19 carries Sunday, including a 74-yard touchdown that was part of a game-deciding 28-point third-quarter flurry by Tennessee. 

The Jaguars allowed 66 yards rushing in the first half, but 40 of those yards came on runs by quarterback Ryan Tannehill. The Jaguars allowed Henry just 26 first-half yards before he rushed for 133 yards and two touchdowns in the second half.

"It's very frustrating," defensive end Calais Campbell said. "We worked hard and prepared like we were supposed to. We played a good half of football and then we came out in the second half and didn't play a complete game. It sucks. I know how good we can be. But it's a matter of results. What you can be doesn't mean anything. It's what you are."

The Titans as a team finished with 219 yards on 33 carries, marking the third consecutive game the Jaguars have allowed 200 yards or more rushing. They allowed 264 yards rushing in a 26-3 loss to the Houston Texans in London in early November, then allowed 216 yards rushing in a 33-13 loss at Indianapolis last week.

That's 699 yards in three consecutive losses to AFC South opponents by a cumulative 101-36. It marked the first time since 2000 the Jaguars have lost three consecutive division games.

"At the end of the day, we've got so many people committed to it and we've got so many things going on," Marrone said. "That's our job. We've just got to figure it out with the guys we have. You've got to keep trying.

"That's how I was raised. You just keep going. You just keep fighting. You keep trying. I don't know any other way to put it. If you just say, 'We're going to get it corrected" and you keep things the same … I can't live like that. That's not how I live my life.

"We're going to go back and look again and probably try to find something else. Obviously, what we've been doing hasn't worked. We've got to get that done."

NOTABLE I

Marrone for a second consecutive week was asked following a loss about a possible change at quarterback from veteran Nick Foles to rookie Gardner Minshew II. Minshew led the Jaguars to a 4-4 record as a starter when Foles was out with a broken clavicle. Marrone said he had no plans to make a change. Foles is 0-3 as a starter, with losses in Week 1 to Kansas City and to Indianapolis and Tennessee the past three weeks. Marrone also specified that he had no plans to fire defensive coordinator Todd Wash. 

NOTABLE II

Marrone also on Sunday was asked about his own job security following a third consecutive one-sided division loss. "I don't worry about it," Marrone said. "It is what it is. If you don't win, you're always going to have a chance to get fired. If you win, you still have a chance to get fired if you don't do it well enough. You just work your butt off and it's up to other people to handle that. I just leave it up to them. I'm not going to waste any time worrying about that. What I'm going to put my time into is how do we coach them better and how do we play better."

NOTABLE III

Jaguars running back Leonard Fournette rushed for 97 yards on 24 carries with two touchdowns Sunday and caught a team-high nine passes for 62 yards. His day would have bene bigger if not for holding penalties on center Brandon Linder on first half runs of seven and 34 yards. Both penalties helped take the Jaguars out of field-goal range and led to punts. "I disagreed with a couple of those calls, but everything doesn't go your way," Fournette said. "It's tough. We were setting ourselves up to be successful. … It gets called back. Looking at the replay, to me it wasn't a hold. But the referees, that's their job. They do what they do."

QUOTABLE I

Marrone: "We're going to work our ass off to get this team right somehow, some way; that's the job."

QUOTABLE II

Fournette: "I'm not going to put it all on Coach Doug. He coaches us, but we're out there as a whole with each other each and every week. It's just tough right now. It's one of those seasons."

QUOTABLE III

Campbell: "There's a lot of football left to be played. All you can do is come out and be the best version we can be of ourselves, work hard and leave it all out there. I know this team is going to keep fighting. There's no quit in us. Don't expect us to just lay down and quit. We're going to keep playing ball."

QUOTABLE IV

Cornerback A.J. Bouye: "We are playing good first-half ball. Were down 7-3 to start the third quarter and then four minutes into the third quarter we're down 28-3. That should tell you my frustration about it. I don't know. It's tough. I don't know."

QUOTABLE V

Foles: "We as men, we as people, we as players that care about one another, have to keep moving forward, have to keep working, have to keep loving one another. At the end of the thing, if you can keep growing through these character moments, through these tough moments, that's where you build something special. It does not just does happen. Everyone wants it just to happen. It just doesn't. That's not part of life. You have to go through these things."
