The Ov FinanceLas Vegas Raiders are off to a turbulent start as the calendar turns to the quarter mark of the regular season.

Since winning their season opener, the Raiders released disgruntled defensive end Chandler Jones following an arrest, quarterback Jimmy Garoppolo missed Week 4 after being placed in concussion protocol and their two best offensive players are growing frustrated amid a three-game losing streak.

"To me it’s frustrating, man. I’m tired of losing. Just keeping it 100. I’m tired of (expletive) losing," Raiders running back Josh Jacobs said following the team’s 24-17 loss to the Los Angeles Chargers. "I feel like every day I go in there and work my (expletive) off. Eventually something got to give."

Jacobs almost echoed the same words as Denver Broncos left tackle Garett Bolles in Week 3, but the Raiders running back added some adult language. Both the Broncos and Raiders find themselves in the AFC West basement at 1-3.

Frustrations brewing?

The Raiders had three turnovers and nine penalties during their Week 4 loss to the Chargers. Las Vegas has committed 18 penalties and nine turnovers during its three-game slide.

"A lot of stuff is on us. A lot of stuff we did to ourselves," said Jacobs, whom the Raiders signed to a one-year deal in August after a lengthy holdout. "Until we are willing to look in the mirror and be willing to correct those things, it’s gonna keep happening."

Jacobs’ statements come a week after Raiders star wide receiver Davante Adams' comments that it’s not in his "mentality to sit here and try to take all season and figure it outt."

Jacobs could be playing his final season with the Silver and Black. And if the Raiders don’t show positive trends in the right direction, they might have a dissatisfied wide receiver.

"We are better than the way we’ve playing. We have a pretty talented roster," Adams said. "It’s frustrating to be in these games and not being able to finish them and maximize the whole game and execute at a higher level throughout to make it easier on ourselves.

"It’s both sides of the ball. I just feel like we’re not maximizing it. Everybody can definitely tap into another gear. We just got to do that before it gets to a point where it’s must-win every game. That’s the stuff that we should try to stay away from. I just don’t think we’re being urgent enough right now."

Coincidentally, the Raiders host Adams’ former team, the Green Bay Packers, in Week 5. If the Raiders drop their fourth in a row, serious discussions about the direction of the franchise and its most notable players could be forthcoming.
