NFL Week 3: Why the San Francisco 49ers Lost to the Kansas City Chiefs

In their Week 3 matchup, the Kansas City Chiefs imposed a crushing 31-10 home victory over the San Francisco 49ers, dropping the cherry red and gold to 0-3 on the 2010 NFL season. 

Their winless start has quickly become a major concern, and I've observed various key team elements that have contributed to their poor performance. 

Here are my thoughts on the top five reasons the 49ers lost to the Chiefs.

Inefficiency on 3rd Down

In order to run an effective offense, the unit must be able to move the chains and convert third downs. 

Against the Chiefs, the 49ers were a dismal 4 of 17 (23 percent) and as a result their offense became stagnant and was unable to gain any momentum. 

On the flip side, they allowed a 50 percent conversion rate (7 of 14), which is unacceptable. 

Since they don't have a star quarterback, San Francisco needs to put itself in easier 3rd-and-short situations. Failing to do so will simply continue this nagging issue. 

Terrible Run Defense

Last season, the 49ers proudly ranked sixth in the league in terms of rushing yards allowed (97.0).

In the first two weeks of 2010, they limited the Seahawks and Saints to 77 and 50 yards, respectively. 

However, they just couldn't get the job done against the Chiefs, allowing the dynamic duo of Jamaal Charles and Thomas Jones to total 192 yards on the ground.

The continuous churning of big gains ultimately sucked the life out of the defense.

Can't Contain the Big Play

The 49ers inexcusably surrendered 9.3 yards per pass attempt and 5.3 yards on every rushing play against the Chiefs, as well as 10.8 yards per punt return.

Whether it be missed tackles or confusion in the secondary, San Francisco was susceptible to big plays and it killed them Sunday.

The big gains gave the Chiefs momentum and allowed their intense fans in Arrowhead Stadium to become a factor.

If there's one consensus that the football world can agree on, it's that Alex Smith isn't an elite quarterback.

If that's the case, then can somebody please explain why he's throwing 42 passes?

Meanwhile, why is the team's star running back, Frank Gore, only rushing the ball 15 teams?

By doing so, the 49ers are lacking a true identity and will remain ineffective. Jimmy Raye is a terrible offensive coordinator, and that is reflected in the results.

No Pass Rush + Bad Pass Protection = ???

The answer to the above equation is simple.

When a team is unable to generate any sort of pass rush as well as allows five sacks, there's nearly no chance for a victory.

The 49ers experienced that first hand against the Chiefs and will need to learn and improve from that deadly combination for the future.
