In a rematch of last season's 30-0 Wild Card round playoff victory for the Chiefs, Kansas City went into Houston to face a Texans team facing revenge. This time around, Houston got the best of Kansas City, 19-12.

The story of the day was self-inflicted wounds and an inefficient offense. Alex Smith completed just 20 of his 37 passes Sunday afternoon for 186 yards. His QBR was not one to be proud of: 68.1.

Here's five noticeable points that resulted from the Chiefs loss on Sunday.

1. Marcus Peters is Great, Most of the Time

Marcus Peters had two interceptions at the cornerback position. That's a great day for any defender in the NFL, but Peters also struggled at times. In the first half, he was beat multiple times on defense against the Houston wide receivers.

Peters also picked up an unsportsmanlike conduct penalty, resulting in a gain of 15 yards for the Texans. In the second half, Peters was able to improve his game and emotions. He was also able to pick up his second interception of the day in the second half.

Chiefs fans get upset quite often with Peters, because they know he has the potential to be great, but often see questionable mishaps from him at corner.

2. Tyreek Hill is Really, Really Fast

Tyreek Hill's speed and versatility was on full display Sunday. Although Hill caught just two passes for eight yards, he was extremely important on special teams.

Hill averaged 15.8 yards on four punt returns and 27.7 yards on three kick returns. He had a 105-yard touchdown return late in the fourth quarter wiped off the board by a holding penalty. He even made a tackle on special teams, too.

3. Penalties Doomed the Chiefs

The Chiefs shot themselves in the foot all day long, including getting the yellow from the men in black and white stripes. Hill's touchdown return that was called back was a huge demoralize at any attempt the Chiefs had at a late comeback.

On the same drive as Hill's would-be touchdown return, the Chiefs took the ball down the field to red zone. With 1:18 remaining, the Chiefs had the ball in the red zone. Offensive linemen Mitch Morse and Eric Fisher each committed false start penalties, making it even more difficult to score.

4. The Defense Did It's Job

After struggling mightily in Week 1 against San Diego in the first half, the defense for the Chiefs did what it had to against Houston on Sunday. Derrick Johnson led the unit with 11 tackles and Peters forced the two turnovers.

Johnson, Tamba Hali, Justin March-Lillard and Ron Parker each registered sacks on the day. They were able to force Texans quarterback Brock Osweiler to make difficult throws and move out of the pocket.

Obviously the defense could have done more, but at the end of the day you really ask one thing of your defense: give your offense a chance to win the game. They did exactly that. They weren't too flashy and make mistakes at times, but they did what they had to do to keep the team in the game.

5. Offense Failed on 3rd Down

The Chiefs converted just three first downs out of 14 attempts against the Texans. The offense often times caught themselves in third and long situations. Smith struggled at times in the pocket while being pressured. He really had a hard time completing short passes on first and second down, which resulted in the offense having to make long passes on third down.
