That's key, because the other team fighting for first place, the 6-4 Denver Broncos, already has one division loss. That came last week when the Chargers invaded Mile High and left with a 32-3 victory.
"They are a good team," said Steve Gregory of the Broncos. "They've hit a rough patch here lately, but they came out and played hard, but we got the best of them."

A month ago, it seemed a given that Denver would win both of its games against the Chiefs and its remaining game with the Oakland Raiders. But just last week, Denver dropped its fourth consecutive game; the Chiefs beat the Pittsburgh Steelers; and the Raiders topped the division-leading Bengals.
"A team coming off two big wins like Kansas City is, I think helps our guys," Norv Turner said. "The most important thing for them is to put the film on and when we watch our first game, there are some physical matchups and there are some plays that we made because we were in the right place at the right time."
Now, the pressure is squarely on the Broncos, especially if the Chargers beat the Chiefs on Sunday. If that happens -- and if Denver loses any of its three remaining divisional games -- San Diego will all but lock up the division crown and the home playoff game that comes with it.
But if the Chargers lose to Kansas City, it opens the door for the Broncos to not only get back into the division race, but to reclaim the tiebreaker as well.
"It feels great [to lead the division]," Malcom Floyd said, "but Kansas City just beat Pittsburgh, so we have to get ready for them."
