The Kansas City Chiefs (7-5) host the San Diego Chargers (3-9) on Sunday at Arrowhead Stadium for the second meeting between these two teams in the past three weeks.

The Chiefs won the first meeting 33-3 down in San Diego three weeks ago.

With the Chiefs carrying plenty of momentum heading into this game, let's take a look at 12 stats to know about Sunday's matchup:

1. Chiefs lead the all-time series with the Chargers, barely

The Chiefs and Chargers will meet for the 111th time in franchise history on Sunday, with the Chiefs holding a 55-54-1 overall advantage in the all-time series.

It will be the 44th time these two teams have played one another at Arrowhead Stadium, where the Chiefs hold a 24-19 advantage, including an 8-4 record in December.

Overall, the Chiefs have 203 franchise wins over AFC West opponents, which is the most for any team in these inter-division affairs.

3. Chiefs are the hottest team in the AFC right now

The current six-game winning streak for the Chiefs is the best mark in the AFC right now. After starting the season 1-5, the Chiefs have caught fire on both sides of the ball and through many significant injuries to improve to 7-5 on the season.

During this winning streak, the Chiefs have outscored their opponents 194-81. The average score of those games would be 32.3 to 13.5, which is pretty good.

4. Jeremy Maclin and Alex Smith heating up

Over the past two weeks, Smith and Maclin have hooked up 18 times for 255 yards and 3 touchdowns, including 11 first-down completions and 3 plays of 30 yards or more.

In the second half of games this season, Maclin is averaging 15.1 yards per catch and has 4 of his 5 touchdowns.

5. The odds are currently in their favor

According to ESPN Stats and Analytics, the Chiefs currently have a 93 percent chance to make the playoffs.

But stats and numbers aren't going to help the Chiefs in their final four games of the season, and we've already seen that anything can change in a short period of time.

Four games ago, the Chiefs were below .500 and saying it was about "taking it one week at a time."

That's the same approach that got them here and it won't change moving forward.

6. Defense continues to create turnovers

The Chiefs defense intercepted 3 passes in the fourth quarter of last week's game against the Oakland Raiders, which was the catalyst for them winning their sixth straight of the season.

Overall, the defense has forced 23 takeaways on the season, which ties them for third-most in the NFL.

Their 17 interceptions rank second in the NFL, only behind the Carolina Panthers (19), who are also the only team with a better giveaway-takeaway ratio than the Chiefs (plus-13). The Panthers are at plus-14.

Marcus Peters leads the Chiefs with 5 interceptions, which also ties him for third-most in the NFL and is the best mark among rookies.

The Chiefs defense has as many players with multiple interceptions this year (6) as they had total interceptions all of last year (6).

Overall, teams are 118-44 this season when winning turnover battle this season.

Over the last 20 seasons (1996-2015), the Chiefs are 97-41 when winning the turnover battle.

7. Alex Smith is playing at a very high level

He's thrown 305 consecutive passes without having an interception, which ranks third best in NFL history and is just 4 shy of passing Bernie Kosar (308) for second all-time. He's 54 away from passing Tom Brady (358) for the most in NFL history.

Smith is 52-18-1 in his career when he doesn't throw an interception.

With his touchdown rushing last week over the Raiders, Smith improves to 8-0 in his career when he runs for a touchdown.

During this current six-game winning streak, Smith has completed 67 percent of his passes for 1,270 yards with 8 touchdowns and no interceptions. He has 13 plays of 25 yards or more during that time as well.

Although it comes with the second-fewest attempts in the league (12 of 29, 3 TDs), Smith has the best passer rating in the NFL on passes that travel 21 yards or more through the air at 125.6.

8. Despite struggling to pick up wins, Chargers are gaining plenty of yards offensively

Led by quarterback Philip Rivers, the Chargers are averaging 381 yards per game offensively, which ranks No. 6 in the NFL.

Through the air, Rivers is averaging 298 yards, which ranks No. 4.

9. Tamba Hali needs just one more sack

With one more sack, veteran linebacker Tamba Hali would have 87 for his career and would move into second place on the all-time list for the Chiefs, passing former great Neil Smith (86.5).

Hali has 6.5 sacks this season.

LAST TIME THEY MET

10. Knile Davis leads AFC in kickoff return average

Davis has averaged 27 yards per kick return this season, which is the best mark of any player in the AFC.

In his career (2013-15), Davis has averaged 28.7 yards per return, which is the best in franchise history for a player with at least 50 returns.

11. Chiefs scoring quickly

The Chiefs have 68 points this season on "quick strike drives," which means coming in four plays or less.

That's the best in the NFL.

12. Continuing to rack up YAC

The Chiefs offense is predicated upon the ability of their playmakers to gain yards after the catch, which they have done in bunches this season.

They have 1,700 yards after the catch, which ranks No. 4 in the AFC.

This success is due in large part to the players' ability after the catch, but also Smith's ability to accurately throw these passes to where the receiver isn't having to break stride or slow his momentum to take off after they secure the ball. Individually, Travis Kelce leads all NFL tight ends over the past two seasons with 965 yards after the catch.
