The Kansas City Chiefs opened the season with authority on Sunday afternoon, defeating the Jacksonville Jaguars by a score of 40-26.

Here are 10 interesting notes from the game.

1. Sammy Watkins had himself a day.

There are good starts to the season and then there's what Watkins did on Sunday.

The veteran receiver hauled in nine catches for a career-high 198 yards and three touchdowns in the victory, weaving through and often running right by the Jaguars' heralded defense.

And what made his performance all the more amazing is how quickly the numbers piled up. Watkins was in the end zone on the Chiefs' first and third possessions - notching scores of 68 and 49 yards – while blowing away his previous career-high in receiving yards before the game even hit halftime.

Watkins was just the fifth player since 2010 to rack up 175+ receiving yards in the first half of a game and went on to tally the fifth-most receiving yards (198) overall in a single game in franchise history. He's also just the fourth player in NFL history to amass 175+ receiving yards and 3+ touchdowns in a season-opener, joining Irving Fryar (1994), Frank Clarke (1962) and Hugh Taylor (1947).

2. The man getting Watkins the ball, Patrick Mahomes, wasn't too shabby either.

Mahomes came out on fire, tallying 211 passing yards in the first quarter alone. It marked the second-most prolific first quarter in terms of passing in NFL history, trailing only Peyton Manning's 247 yards in 2004.

He went on to record 378 passing yards in the game – the second-highest mark of his career – to go along with three touchdown passes and a 143.2 passer rating, which was also his second-highest mark during his time in the NFL.

Additionally, Mahomes now has 11 300-yard performances to his name in just 18 career starts. His 5,759 passing yards and 53 touchdowns are also the most ever through a quarterback's first 20 career games, breaking the record with two games to spare.

And as Sports Radio 810's Soren Petro points out, Mahomes has been ridiculously good on the road during his brief career.

3. The duo of tailbacks Damien Williams and LeSean McCoy was effective.

Williams and McCoy form one of the better backfields in the NFL, and it was on full display in Sunday's victory.

Williams also found the end zone for the 11th time in his last seven games.

4. Nine different receivers caught a pass for the Chiefs on Sunday.

Mahomes connected with nine different players on Sunday, as Watkins (9), Williams (6), Travis Kelce (3), Tyreek Hill (2), Anthony Sherman (1), McCoy (1), Blake Bell (1), Darwin Thompson (1) and Demarcus Robinson (1) all caught a pass.

Interestingly enough, it marked the Chiefs' largest number of pass-catchers since last season's Week 5 victory over Jacksonville.

5. Those performances all helped Kansas City score on each of their first seven drives.

Kansas City came away with points on each of their first seven possessions, notching four touchdowns and three field goals.

The Chiefs have made a habit of scoring early, and it continued on Sunday.

6. It marked the 19th (!!) straight time that the Chiefs scored 26+ points.

Kansas City scored at least 26 points for the 19th-straight game on Sunday (including the postseason), tying an NFL record.

It's also worth mentioning that the Chiefs have scored at least 26 points in every single one of Mahomes' starts under center.

7. Kansas City also became the first team to score 40+ on the Jaguars' home turf in quite a while.

The Jaguars feature one of the top defenses in the NFL, making Kansas City's 40-point outing all the more impressive. In fact, Sunday's game was the first time that Jacksonville yielded 40+ points at home since 2014, snapping a streak of 39-straight games.

8. Frank Clark tallied an interception in his first game with the Chiefs.

The veteran linebacker nabbed the second pick of his career late in the contest, hauling in a batted pass. It marked the Chiefs' second takeaway of the game following linebacker Damien Wilson's forced fumble in the third quarter.

9. The victory marked the Chiefs' fifth-consecutive winning-performance in season-openers.

Kansas City has won five-straight season-openers, which is the third-longest active streak in the NFL. The Chiefs have won six of their seven season-openers under Head Coach Andy Reid and all five road contests.

10. Dustin Colquitt is timeless.

Colquitt embarked on his 15th season with the Chiefs on Sunday, joining fellow punter Jerrel Wilson as the only two players to spend 15+ years with Kansas City.

The veteran punter is now just one game shy of matching Pro Football Hall of Fame guard Will Shields for the most games played (224) in Chiefs' history.
