Norv Turner was asked Sunday whether he could remember facing a more generous opponent, and the Chargers coach sifted through more than three decades worth of memories in vain. "I can't," Turner said finally. "I'm sure we have at some point." The Chargers certainly took advantage of their hospitable hosts. The Kansas City Chiefs committed six turnovers, five of them in the first half, and San Diego rolled to a 37-20 victory and sole possession of first place in the AFC West.
