Any hope they have of going from the bottom to the top of the division rests with ending the divisional streak which began on Nov. 28, 2004, the day the Raiders beat the Denver Broncos 25-24.
Given that the Raiders were trampled for 198 yards on 25 carries by LaDainian Tomlinson and have been giving up rushing yards in bunches all season, it comes as no comfort that the Chiefs' Larry Johnson showed signs of breaking out of his rushing slump with 119 yards on 31 carries in a 27-20 win over the Cincinnati Bengals.
After a promising start, the Raiders played their worst game of the season against San Diego.
Raiders coach Lane Kiffin was blunt in his assessment.
"What happened today is we came out and played like really bad football teams play," Kiffin said. "We turned the ball over. We gave up sacks. We didn't stop the run. We didn't run the ball and we got penalties. It's very easy to see how that game got out of hand.
"We were a bad team today. But bad teams continue to stay bad teams. We've got to go back to work tomorrow and get better and win the next game and get rid of this game and don't let this game beat us next week."
The Raiders will look to restore the luster to a running game that came into the Chargers game ranked No. 1 in the NFL with an average of 194.2 yards per game.
Against San Diego, the Raiders fell behind 14-0 in the first quarter and weren't able to be as persistent with the run as they would like.
They finished with 53 yards on 22 carries, while the Chargers ran for 206 yards on 32 tries.
LaMont Jordan, listed as doubtful entering the game with a lower back injury, had a rough go of it, gaining just 42 yards on 18 carries.
"You have to give San Diego credit, but we need to execute better if we want to run the ball," Jordan said.
In terms of dealing with Johnson and the Chiefs, the Raiders will need to be better at the eight-man fronts which failed them against Tomlinson and the Chargers.
Oakland discovered that missing tackles against someone as elusive as Tomlinson gave him room to run in the secondary.
"When you play eight in the box and a runner gets past the first line of defense, it's a footrace," safety Stuart Schweigert said.
Quarterback Daunte Culpepper, after six quarters leading the offense in which the Raiders ran the ball 74 times and passed 25, struggled trying to lead Oakland with a passing attack.
Culpepper was 24-for-37 for 230 yards, one touchdown and two interceptions, plus a lost fumble late in the last 10 seconds of the first half when Oakland could have tied the score.
