Peyton Hillis said he can't explain why he's struggled so badly in his first season as a Chief. When Hillis hasn't battled an ankle sprain, he's been unproductive on the field. In seven games, he's averaged just 3.75 YPC, scored no touchdowns and lost two fumbles. "There's something to this that I can't figure out," Hillis said. "It takes its toll on you. It's hard sometimes to get out of that rut."
