Mahomes completed 27 of 36 passes for 337 yards and three touchdowns while adding 18 rushing yards and a TD on five carries in Sunday's 33-29 win over the Browns.
The 25-year-old superstar has never lost in September in his career, but that streak looked to be in jeopardy when Cleveland took a 22-10 lead into halftime. However, Mahomes quickly got to work on the comeback after intermission, and he hit Tyreek Hill for a 75-yard TD on a prototypical one-play drive midway through the fourth quarter. Mahomes will face another tough defense in Baltimore in Week 2, but he's proven he can put up big numbers against any opponent.
