Against a Colts front seven that held Houston's running backs to just 29 yards on eight carries in the Wild Card Round, Kansas City used the run to set up an early lead -- Tyreek Hill's 36-yard sweep with six minutes left in the first quarter was the game-winning score -- leaned on Williams to pick up three key fourth-down conversions and rode it for a clock-killing, win-sealing drive in the final frame.
