What happened: Kansas City entered the week leading the league in yards per game after two weeks. It faced fourth down against Indianapolis with the lead available. Rookie Jalen Royals caught his first NFL touchdown from Mahomes to move back in front.

Why it matters: Trusting a rookie in that spot shows rare confidence in young depth. Converting fourth downs for a lead forces defenses to defend every snap. That fearlessness keeps KC as the AFC standard until someone knocks them off.
