Here are 10 stats to keep in mind as the Kansas City Chiefs (4-5) travel to take on the San Diego Chargers (2-7) Sunday afternoon at Qualcomm Stadium in San Diego.

1. Here's to hoping the streaks continue on Sunday

The Chiefs are riding high after winning their last three games, while the Chargers are hoping the bye week has recharged them after losing five consecutive games.

Those five losses have been by a combined 25 points, with each game being within one possession, including the past two over the Baltimore Ravens and Chicago Bears (the Chargers lost by a field goal in each game).

2. Scoring points against the Chiefs defense has been difficult

Over the past five games, the Chiefs defense has allowed just 14 points per game, which is the best in the NFL over that span.

They've also been particularly good in short-yardage situations.

On third-and-1 and fourth-and-1 situations, the Chiefs defense has allowed a first down just 38.5 percent of the time, which is the best mark in the NFL.

The NFL average is 66.7 percent.

3. Playmaking rookie pacing Chiefs defense in turnover department

One of the best stories of the season thus far has been the play of first-round pick Marcus Peters, who leads the Chiefs with 4 interceptions through the first nine games of the season.

Overall, the Chiefs are plus-8 in the turnover department, which ties them for second-best in the NFL in that category. Their 16 takeaways have led to 72 points, which ranks third in the NFL.

The Chiefs have given the ball away just eight times this season, which is third-best in the NFL.

4. Alex Smith doesn't put his defense in bad situations

Smith takes care of the ball—that's kind of his thing.

He's attempted 228 consecutive passes without throwing an interception, which ranks as the best mark for any quarterback in the NFL this season. He's also just 6 attempts away from breaking the franchise record of 233 set by Steve DeBerg back in 1990.

Smith is also still on pace for the most passing yards in single season in his career, and he already has 22 completions of 25-plus yards, which is just 6 shy of tying his career high of 28 set back in 2011 with the San Francisco 49ers.

Against the blitz this season, Smith has a passer rating of 104, which ranks fifth in NFL. Smith has earned that rating despite being sacked 30 times, which is the second-most for any quarterback this season (Russell Wilson-33).

5. Justin Houston had monstrous games vs. Chargers last season

Houston had 5 sacks in two games against the Chargers last season, including a dominating performance in Week 17, when he picked up 4 sacks and almost broke Michael Strahan's NFL record of 22.5 sacks in a single season.

Houston finished with 22.

Over the past two games, Houston has 3.5 sacks and helped lead a Chiefs defense to three consecutive victories.

6. Charcandrick West among elite company

Over the past three games, West has averaged 137 total yards from scrimmage, which is only behind Pittsburgh Steelers receiver Antonio Brown and Minnesota Vikings running back Adrian Peterson.

Not bad for the second-year player in his first few games of action as a lead back.

7. Cairo Santos approaching franchise record

Santos has been fantastic for the Chiefs this season on both his field goals and particularly, his kickoffs.

Last year as a rookie, Santos had a touchback percentage of 32.9 percent on 79 kickoffs. Through the first nine games this season, Santos has a touchback percentage of 62 percent.

Santos already has three field goals of at least 50 yards, which puts him one away from tying former great Nick Lowery for the franchise record of 50-plus yard field goals in single season.

Lowery set that record back in 1980.

8. The Chargers have struggled to win the field position battle this season

The Chargers offense has an average starting field position of the 21-yard line, which ranks last in the NFL.

San Diego's opponents have an average starting field position of the 32-yard line, which also ranks as the worst in the NFL.

On the flipside, the Chiefs offense has a starting average field position of the 31-yard line, which ranks second in the NFL.

9. The Chargers offense is really, really pass heavy

Philip Rivers has attempted more passes (390) than any other quarterback in the NFL this season. The Chargers average 329 net yards passing per game, which ranks as the best mark in the NFL.

The Chargers have run the ball just 34.8 percent of the time in the first half of games this season, which ranks as the third-lowest percentage of time in the NFL.

10. Key thing to watch on Sunday? Yards after the catch for Chiefs offense

The Chiefs offense has been largely predicated on the ability for the receivers to gain yards after the catch.

That's the way it's designed, and it's worked.

The offense ranks fourth in the NFL with 1,195 yards receiving coming via yards after the catch. Guys like Jeremy Maclin and Travis Kelce have excelled in this area with their playmaking ability, and it's a thing to watch on Sunday because the Chargers have allowed the second-most yards after the catch in the NFL this season with 1,298.

Overall, the Chargers defense has allowed 6.34 yards per play, which ranks second to last in the NFL.
