Patrick Mahomes is often the hero for the Kansas City Chiefs, but he heaped praise on their defense after a Week 14 win over the Denver Broncos, in which he threw three interceptions.

Mahomes and the Chiefs improved to 10-3 for the season with a 34-28 win in Denver, which eliminated the 3-10 Broncos from postseason contention.

The Kansas City quarterback recorded his 24th career game with at least 300 passing yards and three touchdown passes, surpassing Dan Marino (23) for the most such games by a player in his first six seasons in NFL history.

His 352-yard effort took Mahomes to 4,160 passing yards on the season. In doing so, he joined Peyton Manning as the only players in NFL history with at least 4,000 passing yards in five of their first six seasons.

But Mahomes, who threw three touchdowns, also produced a trio of turnovers, two of which took place in the second quarter and culminated in Broncos touchdowns that allowed the hosts back into a game they had trailed 27-0.

His third in the fourth quarter gave the Broncos, quarterbacked by Brett Rypien late on after Russell Wilson left the game with a concussion, the chance to take the lead.

But Rypien was intercepted by L'Jarius Sneed on the subsequent drive, allowing Mahomes and the offense to kill the clock and clinch a 14th successive win over Denver.

Asked about his interceptions, Mahomes said: "Just three bad decisions. When you look at them, the first one, I probably just could've taken the easy throw to the outside, and I forced it to [Travis] Kelce.

"The second one, I was just trying to burn it, and he [Patrick Surtain II] made a hell of a play. And the third one was bad-bad just because the situation. We're in field-goal range - especially here in altitude and no one else is open - so [I] just throw the ball away and let [kicker] Harrison [Butker] end the game.

"Luckily for me, the rest of the team stepped up. The defense made a lot of stops in critical moments when we were putting them in some bad situations."

Head coach Andy Reid, though, expressed support for his former MVP quarterback and the aggressive nature of his play that has so often paid dividends for the Chiefs.

"Every quarterback that's played in this league a while has a game like that," said Reid. "The one great thing about him is he kept firing and had a lot of big plays.

"You can't take away the three interceptions, but there sure were some good ones in between those, and it's a great learning experience."
