KANSAS CITY, Mo. (AP) There may be no more valuable player on the Kansas City Chiefs than Jamaal Charles, the game-breaking running back with the slick moves and world-class speed.
His success this season could be closely tied to that of Knile Davis.
The Chiefs have given Charles a remarkably light load in training camp and preseason games in an effort to keep him healthy, and that has meant more work for Davis.
But if his backup can be productive enough, the Chiefs may continue to give Charles a lighter load once games start to count, keeping Charles fresher over the 16-game grind than he has been the past couple of years.
