KANSAS CITY, Mo. (AP) _ Jamaal Charles is about as difficult to catch in the locker room as he is in the open field, where he routinely makes defenders look foolish with his swiveling hips and world-class speed.
But if you catch him for a moment, you'll quickly learn why he's among the best in the NFL: The pursuit of perfection drives him every day.
Charles enters the weekend third in the NFL and tops in the AFC with 1,011 yards rushing, and his 4.6 yards per carry is tied for seventh among those with at least 100 attempts. He also has nine TDs rushing, one behind league leader Adrian Peterson of the Vikings.
