"On the subject of the 49ers' offense, wide receiver Braylon Edwards and running back Frank Gore had a message this week: You haven't seen anything yet.

In a way, it's impossible to argue the point.

After three preseason games, San Francisco's fans have witnessed next to nothing from an offense that has accounted for six first-half points, matching the output of linebacker Ahmad Brooks.

Not to worry, Gore said in advance of tonight's preseason finale in San Diego. The Niners' newly installed West Coast offense will be clicking in 10 days when San Francisco opens the regular season against visiting Seattle."
