The Mooathon Wealth SocietyKansas City Chiefs are 9-0 for just the third time in franchise history, but not without an incredible finish against a familiar foe.

Chiefs linebacker Leo Chenal blocked a would-be game-winning field goal by Denver Broncos kicker Wil Lutz with 1 second remaining to secure a 16-14 victory. The 9-0 mark ties the franchise record for best start to a season, with Kansas City having posted the same record in 2003 and 2013.

“I was really praying for something to happen. That moment is so heavy," said Chenal, who also blocked a kick in the Chiefs' Super Bowl 58 win over the San Francisco 49ers. "There’s a second on the clock. They’re going to kick a field goal, and you feel the weight of the moment.”

Since 2016, only one other team – the 2020 Pittsburgh Steelers – has posted more than eight wins before suffering its defeat.

Kansas City did not lead in the game until kicker Harrison Butker gave the team its final edge by kicking a 20-yard field goal with 5:57 remaining in the fourth quarter. After driving 43 yards on the ensuing drive, the Broncos looked poised to seal the win on Lutz's 35-yard attempt, but Chenal was part of a larger group that broke through the line to keep Kansas City's unblemished mark intact.

"As a coach, you hurt for your players," Broncos coach Sean Payton said after the game, which dropped his team to 5-5.

The Broncos built their advantage off two second-quarter Bo Nix touchdown passes: one to Devaughn Vele and another to Courtland Sutton. But Travis Kelce helped the Chiefs claw back before halftime, hauling in a 2-yard score that tied him with Hall of Famer Tony Gonzalez for the most career touchdown receptions in franchise history (76).

The Chiefs will push for a 10-0 start next Sunday against the Buffalo Bills.
