Before San Francisco added free agent Brian Westbrook to its backfield this week, the 49ers made it a point to consult with Frank Gore first. The two-time Pro Bowl running back, who has led the team in rushing each of the past five seasons, quickly gave his blessing.

“I thought if he could help my team get better and help us go to another level, I’m fine with it,” Gore said Tuesday after San Francisco’s single practice. “He’s been a great back in this league for a long time. I already started asking him questions, but I feel he can help me get better.”

San Francisco needed help in its backfield after the surprisingly abrupt retirement of Glen Coffee after one year. Even when Westbrook is up to speed with the power-based running game the 49ers employ, he’ll remain an understudy to Gore. Coach Mike Singletary made that point clear when San Francisco announced the Westbrook signing.
