After just two starts with the Raiders, Jason Campbell has been benched in favor of Bruce Gradowski. Raiders coach Tom Cable announced the switch after practice Wednesday, hoping the spark that Gradkowski provided in the second half of last weekend's 16-14 victory over the St. Louis Rams can carry over the rest of the season. "The reasons are pretty simple," Cable said. "First and foremost is the energy and the level of intensity that was brought into the huddle when he came into the game. The way the guys responded around him. And, obviously, scoring points. ... That's what we're about. If we can get this thing to where we can score 24 points a game, I think we'll be very tough to beat."
