Takeaways as Chiefs outlast Falcons 22-17 on Sunday Night Football

Patrick Mahomes and the Kansas City Chiefs keep winning.

Kansas City on Sunday Night Football went to Atlanta and soared over the Falcons with a 22-17 win, moving it to 3-0 on the young campaign.

It wasn't always pretty and Mahomes was far from his best for the second straight season, but Atlanta's inability to score in the second half proved decisive. It came down to the final drive, but the Falcons failed to convert a 4th and short via Bijan Robinson that sealed the deal.

Falcons head coach Raheem Morris after the game declined to comment, saying he likes his money.

That play could've been the reason Atlanta won as a flag would've seen the Falcons proceed to the one-yard line. Instead, the ball went back to Kansas City, who went three-and-out. Atlanta could've seen out the game from that point.

Kansas City last time out benefited from a pass interference call on a 4th and 16 against the Cincinnati Bengals, which helped set up its last-second field-goal win.

Young receivers shine under the lights

QB play between Mahomes and Cousins wasn't always at its best, but both stars received vital help from their young wideouts.

For Kansas City, it was second-year option Rashee Rice. Rice came up clutch with 12 catches for 110 yards and a touchdown, his second 100-yard game of the season. Travis Kelce continued to go under the radar with just four catches for 30 yards.

Atlanta received solid play from Drake London as the third-year wideout continues to blossom. London logged six catches for 67 yards and a touchdown to follow up on his solid outing at Philadelphia. Darnell Mooney also came up big with eight catches for 66 yards, but Atlanta will be disappointed with Bijan Robinson and Tyler Allgeier struggling on the ground. Robinson, specifically, averaged just 1.9 yards per carry en route to 31 rushing yards.

Carson Steele steps up as RB1

With Isiah Pacheco sidelined for a while due to injury, the Chiefs turned to two faces to pick up the running load. Those two were veteran Samaje Perine and rookie fullback Carson Steele.

Perine recorded six carries for 25 yards and three catches for 15, but Steele provided the better impact. The undrafted free agent rushed for 72 yards on 17 carries, good for a 4.2 average and a long of nine. It may not have been a headline-grabbing breakout game, but he may have earned the trust of Andy Reid and Co. to earn more carries moving forward.

Rookie wideout Xavier Worthy logged three rushes for 13 yards.

Falcons enter crucial stretch

With the Falcons now 1-2, their next three games could prove pivotal down the line. With the Pittsburgh Steelers, Eagles and Chiefs out the way, up next are three divisional games. First is Derek Carr and the New Orleans Saints at home, as Carr came back down to earth in a Week 3 loss to Philly after a hot opening two games.

Then Atlanta will again be at home against Baker Mayfield and the Tampa Bay Buccaneers, who are also off to a solid start. The three-game stretch concludes at the Carolina Panthers, who, for now, are a slightly different team with Andy Dalton under center instead of Bryce Young .

If Atlanta has serious aspirations of contending this season, it should go 3-0 and make some noise as the next four games after will be versus the Seattle Seahawks, at Tampa Bay, home to the Dallas Cowboys and at New Orleans.

How long will Kansas City remain unbeaten?

Last season saw a vulnerable Chiefs side lose more than a handful of regular-season games. This year, they've already faced three tough teams in the Baltimore Ravens , Bengals and Falcons and have gone unscathed despite being shaky in the latter two games.

How long can the Chiefs stay flawless? They're on the road next against a Los Angeles Chargers side facing uncertainties regarding Justin Herbert's injury. Then it's a home game against Carr and the Saints, which should be a win on paper.

The next game is a Super Bowl rematch on the road against the San Francisco 49ers , but Kyle Shanahan's team is dealing with multiple key injuries that may remove the excitement from the atmosphere. Then it's at the Las Vegas Raiders and home to the Buccaneers and Denver Broncos before a Week 8 clash at the Buffalo Bills .

If Kansas City can stay healthy, a 7-0 start before heading to Josh Allen's territory is certainly on the cards.
