The Oakland Raiders entered Week 13 on a two-game losing streak and in desperate need of a win to stay alive in the AFC West.

In front of them were the red-hot San Diego Chargers on a four game winning streak.

The Raiders went into San Diego and won in all phases of the game.

Jason Campbell played mistake free football, Darren McFadden and Michael Bush brought the Raiders running game back to life, and the Raiders' defense got pressure on Philip Rivers all day.

The Raiders have now improved to 6-6 and 4-0 in the AFC West.

They remain two games behind the Chiefs.

Stats: 10 for 16, 117 yards, 1 touchdown, 0 interceptions, 37 rushing yards, 1 touchdown rushing

Grade: A

I know Campbell did not light up the stat sheet but he managed the game and played mistake free football during the Raiders' 28-13 win.

Campbell got rid of the ball quickly and only got sacked one time.

He also made plays with his feet to avoid the rush and picked up some key first downs

The Raiders relied heavily on the run but when Campbell had to make plays, he made them.

Stats

Darren McFadden: 19 carries, 97 yards, 1 touchdown, 5.1 yards per carry

Michael Bush: 23 carries, 95 yards, 1 touchdown, 4.1 yards per carry

Grade: A+

The Raiders running game was missing during their two-game losing streak but Darren McFadden and Michael Bush helped put them back on the map. 

The Raiders running game had a monster day, totaling 251 yards on the ground.

McFadden and Bush ran hard all day picking big first downs and scoring two of the Raiders' four touchdowns.

This was a big game for McFadden who totaled only 16 rushing yards in his two previous outings.

The running game was huge for the Raiders as they dominated the time of possession, holding the ball for over 38 minutes.

Grade: A

The Raiders' win over the Chargers was a huge boost of confidence for the Raiders' offensive line.

They did a great job protecting Jason Campbell who was only sacked once and they allowed Darren McFadden and Michael Bush to contribute to the Raiders' 251 yards on the ground.

Besides some false start penalties, the Raiders' line did a great job blocking for McFadden and Bush throughout the game.

Grade: A

There seems to be a theme here as the Raiders have earned A's all across the board thus far. 

The Raiders' defense did a phenomenal job putting pressure on Philip Rivers and completely shutting down Mike Tolbert and the running game.

The Raiders' defense forced Rivers to be uncomfortable with his throws and brought him down four times.

With sacks from Michael Huff, Tommy Kelly, Lamarr Houston, and Kamerion Wimbley, the Raiders' defense was the key to victory.

The defense forced two turnovers, held the Chargers to rush for just 21 yards, and held them to13 points.

Grade: F

Despite the huge win for the Raiders, there was one thing that Coach Tom Cable is not happy about—penalties.

The Raiders committed 13 penalties for 105 yards.

The Raiders are the most penalized team in the league and fortunately enough for them, it did not interfere with their big win over the Chargers.

This is something the Raiders definitely need to work on for the remainder of the season.
