JACKSONVILLE – Doug Marrone's thoughts remain singular.

"When I'm in this building, my thoughts are, 'How are we going to get ourselves to play a better game?' We're not playing well,''' he said.

That's how the Jaguars' head coach began his weekly media availability Wednesday, and such were his thoughts throughout the session. The Jaguars are struggling. What matters to Marrone is how to change that, and on Wednesday he reiterated said Monday following a fifth consecutive one-sided loss:

Confidence is a major issue.

And a challenge is how to find it.

"One of the things I talked to the team about was we're not playing with a lot of confidence out there," Marrone said as the Jaguars (4-9) prepared to play the Oakland Raiders (6-7) at RingCentral Coliseum in Oakland, California, Sunday at 4:05 p.m.

"We've got to work on that. You gain confidence by winning games, and we're not doing that. How do you gain that confidence? We have to go back and make sure we know exactly what's going on, feel good about during the week, feel good about the plan."

Marrone said a key is being sure what is put into the game plan are things the players are capable of executing.

"We really as a staff – and players – have to take a look at what we can handle and not handle, and take it out and live with what we're going to play with – schematically and in the game," Marrone said. "I think that's the most important thing."

The Jaguars were officially eliminated from the postseason this past Sunday and have lost their last five games by a cumulative score of 174-57. They have not led in the second half since beating the New York Jets at TIAA Bank Field in Jacksonville on October 27. Marrone said it's not "rocket science" to realize players and coaches are thinking this week about their jobs, and careers.

"Everybody's fighting to maintain … to try to stay in the league," Marrone said. "Whether it's players, by doing a good job, being able to perform so they can keep a job. Or whether it be coaches doing a good job with their position group. Or whether it be me trying to win football games.

"I think it's something that we've all talked about. It's easy from an outside perspective to say, 'What do they have to play for? What do they have to do?' We're all fighting for our jobs. When you look at it from that standpoint, each person has to make their own decisions on how to handle those things."
