The offensive struggles continued on Sunday for the San Francisco 49ers in a 27-6 loss at the hands of the St. Louis Rams.

For the second consecutive contest, the 49ers were kept out of the end zone and the team now has nine combined points in those games.

Colin Kaepernick, who completed 20-of-41 passes for 162 yards in Week 8, addressed the recent offensive woes in his postgame press conference.

"We've done different things to try and move the ball down the field," Kaepernick said. "The bottom line is that our performance hasn't been good enough."

Third downs continue to be a concern for the 49ers offense. San Francisco converted on just 3-of-17 third-down attempts against the Rams.

Kaepernick tabbed the excessive amount of penalties as a reason for the inefficiency on third down.

"One thing that jumped out to me is that we had a lot of penalties as an offense and as a team," the quarterback said. "That put us in backed up situations. That's not something you can do against a defense like this and expect to go up and down the field."

The 49ers were missing starting running back Pierre Garçon (foot) and top receiver Anquan Boldin (hamstring) in the game. Mike Davis (hand) and Reggie Bush (knee) were injured against St. Louis and didn't return.

The moving parts along the offensive skill positions made things difficult for San Francisco's offense that mustered just 189 yards and 11 first downs against a tough Rams defense.

"It's difficult," Kaepernick said. "It's something that we have to be able to make up for those things and be able to make plays with other players. We weren't able to do that today."

On one play leading up to a Rams safety in the first quarter, Torrey Smith was standing uncovered on the left side of the field. Kaepernick admitted that he missed the blown coverage that could have provided San Francisco with a big play.

"I didn't see the corner close down on that," Kaepernick said. "That's something I should have adjusted to and gotten us out of that running play."

When asked whether or not he'd be surprised to see the 49ers make a change at quarterback in favor of Blaine Gabbert, Kaepernick told the media that it's not his job to worry about those decisions.

"To me, I'm doing everything I can to win games," Kaepernick said. "Whether they make that change or not is their decision, but I'll give this team everything I have, every week."

Kaepernick echoed what many other 49ers players have said throughout the week that the losses aren't an indication of the team's work ethic. The team is said to be having productive practices throughout the week, but they've been unable to translate that into game situations.

"We have to be able to put a complete game together and show those things on the field," Kaepernick said. "The biggest thing is execution. We have a penalty here, we have a mishap here or there and we get backed up. That's something that we can't do in the division that we play in."

The 49ers will return home in Week 9 and host the Atlanta Falcons before taking their bye week.
