The Kansas City Chiefs entered Saturday as the league's best offense, in yardage (425.6) and in points (35.3) and the third-best passing attack with the most yards per play in football (6.84).
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.
In other words, Kansas City ran Indianapolis into the ground and out of the playoffs.
"They was on a roll, but we on a roll too," Williams said of the Colts, who entered having won 10 of their last 11 games, to NFL Network's James Palmer. "And they came to our house and we had to lay it down."
Adding to the odd nature of K.C.'s home postseason victory, Saturday's win was just the second game all season that Mahomes failed to throw a touchdown pass.
But with a resurgent defense and an emerging running game, Kansas City has finally found balance, just in the nick of time.
