The 2024 NFL season officially launched Thursday night, the two-time-defending Super Bowl champion Kansas City Chiefs defeating the Baltimore Ravens 27-20 in a rematch of the 2023 AFC championship game and the first of this campaign’s 272 regular-season games.

It was a nail-biter to the end, largely dictated by some of the league’s top superstars but also a stage for some apparent up-and-comers. It could also carry major playoff ramifications, K.C. already holding what could be a valuable head-to-head tiebreaker that would set any potential playoff rematch back to Arrowhead Stadium.

In sum? It’s just one game. But, as always, the winners and losers extend beyond the scoreboard:

WINNERS

Chiefs

Their bid to become the first team to achieve a Super Bowl three-peat is off to a good start a year after they lost the seasonal kickoff game at home to the Detroit Lions. Three-time Super Bowl MVP Patrick Mahomes didn't have his best night, but it's pretty obvious this offense is primed to be far more dangerous than it's been in recent years. Next up? Ten days to recover and prepare for the Cincinnati Bengals, who come to Arrowhead for Week 2.

Matt Araiza

After a two-year delay due to a dropped accusation of committing rape while at San Diego State, he made his NFL debut with K.C. A ballyhooed sixth-round pick of the Buffalo Bills in 2022, the “Punt God” averaged 48 yards on three boots, the final one pinning Baltimore deep in its own territory inside the final two minutes.

Rashee Rice

The Chiefs’ No. 1 wide receiver is dealing with his own legal issues after a notorious offseason following his sensational rookie season. Rice is likely to face NFL discipline at some point after being involved in a six-car crash in Dallas, where he was driving a Lamborghini nearly 120 mph this April, according to police. Rice is facing one count of aggravated assault, one count of collision involving serious bodily injury and six counts of collision involving injury. However the league doesn't typically mete out suspensions until the legal process has concluded … which enabled Rice to reel in team highs with seven receptions for 103 yards.

Taylor Swift

The pop mega star ran her personal win streak to six in Chiefs games she’s attended while supporting boyfriend Travis Kelce.

Isaiah Likely’s fantasy owners

After a strong 2023 season, when the second-year tight end became a major component of Baltimore’s offense in the absence of injured Mark Andrews, he appears to be emerging as QB Lamar Jackson’s favorite target. Likely had a 49-yard TD catch-and-run, which greatly contributed to his game-best (and career-high) nine receptions and 111 receiving yards.

Chiefs’ shiny new acquisition

WR Xavier Worthy, Kansas City’s first-round pick after setting a scouting combine record with a 4.21-second 40-yard dash, had quite the regular-season debut – scoring TDs on a 21-yard run in the first quarter and what turned out to be a game-clinching 35-yard scoring reception from Mahomes in the final period. No question Worthy is going to be a problem, probably more so when veteran blazer Hollywood Brown is healthy enough to return to the lineup.

Lamar Jackson

He accounted for 395 yards of offense, including a game-high 122 rushing yards. Not a winning performance, but one that might eventually help him build toward a third league MVP award.

LOSERS

Lamar Jackson

His fumble led to a second-quarter field goal for K.C. Worse, Jackson missed a wide-open Zay Flowers in the end zone on the game’s penultimate play – saying afterward he should have held the ball longer in order to connect with Flowers but didn’t actually target him on the throw in question. Jackson’s record against Mahomes dropped to 1-5.

Ravens’ smudged new acquisition

Baltimore’s big free-agent signing, RB Derrick Henry, finished with 46 yards on 13 carries and concluded the opening drive with a 5-yard TD run. But he seemed to disappear for stretches afterward, and questions will remain as to how well his power style will mesh with Jackson’s elusive one, though Henry’s presence will likely open rush lanes for his quarterback – as it did Thursday.

Isaiah Likely’s fantasy owners

You greedy mothers know you were angry when Likely's toe caught the back line of the end zone on the final play, negating a 10-yard TD that could have meant a Ravens (and fantasy?) win – coach John Harbaugh seemed ready to go for two and the victory – or, at least, send the contest into overtime.

Mark Andrews’ fantasy owners

Two catches, 14 yards, Likely specter. Sorry, y’all.

Travis Kelce’s fantasy owners

(This has nothing to do with Swift.) For others who might love Kelce … three catches for 34 yards.

Justin Tucker

He’ll probably be the rare kicker who winds up in the Pro Football Hall of Fame. But after going 1-for-5 on field-goal attempts beyond 50 yards in 2023, Tucker was wide left on a 53-yarder Thursday.

Harrison Butker

The Chiefs kicker remains wide of the mark elsewhere, but that’s a different story.

Baltimore’s O-line

For a unit breaking in three new starters and dealing with the sudden death of positional coach Joe D'Alessandris, it definitely could have gone worse. But there didn’t appear to be much daylight for Henry. Jackson got bum-rushed by All-Pro DT Chris Jones on his fumble after rookie RT Roger Rosengarten entered the game. And there were the four illegal formation penalties, three on LT Ronnie Stanley. Not. Great.

Chiefs defense

A unit that ranked second in the league last season was scorched for 452 yards – 70 more than it allowed in any of its 21 contests during the 2023 season. In fact, the Chiefs hadn't surrendered this many yards since the end of the 2021 regular season. K.C. also struggled to get off the field on third down, Baltimore converting on half of its 14 attempts. The Ravens are clearly a quality opponent and perhaps not the best barometer of defensive success. But there is likely to be an adjustment period now that former CB1 L'Jarius Sneed and LB Willie Gay have moved to other teams.

‘Dynamic kickoff’ rule

Uh. A high-profile, XFL-style alteration designed to bring the kickoff back to relevance … just hasn’t done so yet. There were 11 kickoffs Thursday but just two non-descript returns, an early suggestion that teams are content to settle for touchbacks that start drives on an opponent's 30-yard line rather than risk game-changing runbacks.
