Last year at this time, the Chiefs offense was putrid, and the smell emanated from the running-back position. But after the first Twitter-related expulsion in Chiefs history, the team waived Larry Johnson. That opened the door for Jamaal Charles, who was a revelation, racking up 1,120 yards in just 10 starts. Where Johnson's runs clogged at the line, Charles found a way into opponents' secondaries and the end zone. And in a Chiefs season of rebuilding, he delighted fans and fantasy-team owners with his electric presence. This season, he's at it again, even if Thomas Jones is inexplicably getting more carries.
