49ers running back Brian Westbrook thought he'd have a bigger role in the team's offense heading into the season. "It's definitely frustrating," he said. "As a player, you always want to play. You always want to go out there and help the team. But, like you said, only having four snaps - it's really hard to help your team." Westbrook's new team will face his old one when the Eagles travel to San Francisco this Sunday night. He acknowledged that Frank Gore's success this season have made snaps hard to come by.
