The Chargers defense is much like Oakland's in that they've both been strong against the run and very mediocre against the pass. San Diego is allowing only 93.8 yards a game and just 3.6 yards a carry, while the Raiders' defense counters with 99.3 and 3.4.
Offensively, Oakland is still trying to find a comfortable rhythm. The running game was virtually non-existent the first three weeks of the season before LaMont Jordan broke out for a career-highs of 126 yards and 26 carries in the win over Dallas.
That took some of the heat off Collins, who passed for 218 yards and extended his interception-less streak to a career-best 149 passes dating back to last season.
''We're going to need that (running game), especially against a team like this,'' Collins said. ''They rush the passer well and they more you can run, the better it does with the play-action game.''
Raiders head coach Norv Turner echoed Collins' sentiments, saying its paramount that Oakland establish the ground game against a San Diego team that is ranked seventh against the run and 21st overall.
''I'd like to see (Jordan) get 25 carries in the football game,'' Turner said. ''It would help us do the things we have to to win the game. That's keep the ball some. Obviously they're a very talented offensive football team but if we can get some run going it would help (Jerry) Porter and (Randy) Moss and the guys in the passing game.''
* The Chargers have won the last three games between the two teams. A win on Sunday would give San Diego it's first four-game winning streak over the Raiders since they swept the season series in 1961 and '62. The Chargers also won both games in 1960 but the franchise was located in Los Angeles at the time.
