The running game came seemingly easy for the Chiefs early on. Kareem Hunt ran with determination and piled up the numbers. Hunt continues to churn hard, but he and the Chiefs’ running game haven’t been getting as far. The offensive linemen say to put that responsibility on their shoulders. “Obviously it hasn’t been going our way lately, not how we’ve wanted it to go,” said Zach Fulton, who has played both guard positions and center this season. “We just have to keep chopping away at it, and we will.” Injuries and lineup shuffling have been an issue. Center Mitch Morse suffered a foot injury in the second game and missed the next five, with Fulton taking over. In the fourth week, guard Laurent Duvernay-Tardif injured his knee and missed the next month. Cameron Erving, acquired just before the season from the Browns, started three games, and Fulton started the fourth. In a 12-9 loss to the New York Giants last week, the Chiefs made a lineup change, with Fulton playing his third position — left guard — in place of Bryan Witzmann, who had started the first nine games.
