welcome back to "first look." in sports, long a profootball, suddenly the oakland raiders are threatening to become relevant again. here is fred roggin. many believe the raiders paid too much for carson palmer. last night he was worth every penny. he dropped back, surveyed the field and threw a strike to denarius moore. the chargers didn't back down. philip rivers defense brought a tremendous catch with two defenders all over him. san diego closed the gap, down 17-10. that's as close as they would get. palmer wanted more, he got it, another touchdown to denarius moore, the rookie quickly becoming his favorite target. raiders took over first place with a 27-4 win. the chargers have dropped four straight.
