Wrap-up: Eagles 27, 49ers 24

Thoughts on the San Francisco 49ers following their 27-24 defeat against the Philadelphia Eagles at Candlestick Park on Sunday night:

What it means: The 49ers are going to have a hard time holding things together after their fifth consecutive defeat to open the season. They appear doomed and it's tough finding likely victories on their upcoming schedule based on how the season has played out so far. The 49ers are suffering breakdowns almost across the board -- even Frank Gore and Joe Nedney proved unreliable Sunday night -- and quarterback Alex Smith isn't good enough to transcend the mistakes. We've gone from wondering whether the 49ers would win the NFC West to wondering how much longer the organization will stick with Mike Singletary as head coach.

Tomorrow's Talker: Cameras showed Singletary ripping into Smith following the quarterback's costly lost fumble. Singletary appeared on the verge of making a quarterback change. Cameras showed backup David Carr speaking on the sideline phone linking to the coaches' booth. Did Smith talk his coach out of making a change? Former 49ers quarterback Shaun Hill made such a successful plea previously. Did Singletary nearly bench Smith? Is a quarterback change coming soon?

Goat(s): There were several from which to choose. Call it a herd. Gore lost two fumbles. Nedney missed a 40-yard field-goal attempt as the first half ended. Smith threw interceptions and lost that fumble after rolling awkwardly to his left against pressure.

Identity crisis: Who are the 49ers? What do they do well? They couldn't run the ball or stop the run well enough Sunday night. They couldn't pass efficiently or stop the Eagles from passing efficiently. It's tough to find one area the 49ers can rally around.

What's next: The 49ers face the Oakland Raiders at Candlestick Park in Week 6.
