KANSAS CITY, Mo. (AP)Patrick Mahomes moved into the rarest of company Sunday, joining Tom Brady and Drew Brees as the only quarterbacks with multiple 5,000-yard passing seasons, and the Chiefs overcame another sloppy start to beat the Broncos for the 15th consecutive time and stay alive for the No. 1 seed in the AFC.

So everything must be good in Kansas City, right?

”There’s not a lot satisfying for me,” Mahomes said shortly after the 27-24 victory.

There was the pick he threw in the end zone and the mechanics that went awry in the second half. There was the fumbled punt return that led to a Denver touchdown, a sloppy snap on a point-after attempt and even a blocked field goal.

Yet the Chiefs (13-3) still managed to escape a 17-13 third-quarter deficit and rally for their fourth consecutive win.

”When I don’t have my best stuff and guys step up and we still win football games,” said Mahomes, who nevertheless finished with 328 yards passing and three touchdowns, ”that’s a good thing.”

Jerick McKinnon had two touchdown catches while Blake Bell and Isiah Pacheco also scored for the Chiefs, who began the day tied with Buffalo for the best record in the AFC; the Bills play Cincinnati on Monday night.

”We’ll watch it,” Chiefs coach Andy Reid said with a smile.

For a while the Broncos (4-12) looked as if they might cap a chaotic week that began with the firing of first-year head coach Nathaniel Hackett in a stunning victory. But a late letdown by one of the league’s best defenses, an another interception from embattled quarterback Russell Wilson, resulted in the first loss for interim coach Jerry Rosburg.

”I saw players and coaches digging in to do all they could possibly do to win that game,” he said. ”That all said, it wasn’t good enough. It wasn’t good enough and I’m heartbroken for those guys because they deserve a win.”

Wilson threw for 222 yards and a touchdown while also running for a pair of scores, the second of them – after two costly penalties on the Kansas City defense – pulling Denver within 27-24 with 6:14 left in the game.

The Broncos got the ball back with just under four minutes to go, too, and picked up a quick first down. But the Kansas City defense stiffened near midfield, and Chris Jones sacked Wilson on fourth-and-2 to effectively end the game.

The Chiefs’ sluggish start against the downtrodden Broncos wasn’t all that surprising. They’ve habitually played down to the opposition, whether it was in their overtime win at Houston or their 34-28 victory over the Broncos three weeks ago.

But the Chiefs also have proven over the years their ability to strike quickly, and they did that after falling behind for the first time Sunday. Mahomes answered with long passes to Toney and McKinnon, a penalty on third down gave them a fresh set of downs, and McKinnon turned a screen pass into a touchdown reception for the fifth straight game.

That streak is the longest for an NFL running back since Bill Dudley of the Lions in 1947.

”If I would have told you I saw it was coming, nah,” McKinnon said, ”but that’s what you put the work in the offseason for, when you’re opportunity comes you’re ready for the moment.”

The Chiefs struggled to maintain momentum after halftime, though, going three-and-out on their first three possessions. And the Broncos, with their third play-caller of the season in offensive coordinator Justin Outten, capitalized with a 63-yard touchdown drive that gave them a 17-13 lead late in the third quarter.

Then the Chiefs began looking like the Chiefs. And the Broncos like the Broncos.

Mahomes led the AFC West champs briskly downfield before hitting Bell from 17 yards for his first regular-season touchdown catch. And on the very next play, Wilson threw a wobbler under pressure that L’Jarius Sneed picked off, setting up McKinnon’s second touchdown catch of the day and his eighth in the past five games.

The Broncos scored in the fourth quarter to give themselves a chance before Kansas City put the game away.

”When you win and you don’t feel like you play you best ball, that’s a really good thing,” Mahomes said. ”We have to find a way to, for four quarters, play our best football when we get to the playoffs. And I feel like we haven’t done that.”
