The storyline
Chargers aim to show Pro Bowlers Vincent Jackson and Marcus McNeill are expendable and the Chiefs open up their renovated stadium looking to become a factor in the AFC West.
Why you should watch
Chargers' gamble on McNeill and Jackson will make every game interesting. Rookie RB Ryan Mathews takes over for L.T. Matt Cassel's second season in Kansas City could be his last without marked improvement.
