SAN FRANCISCO OFFENSE: It's not common that Alex Smith would have the edge over a secondary, but that appears to be the case in this instance. Dallas has so many injuries at corner that they spent Tuesday afternoon signing guys off the street.
As long as this game is close and the 49ers can stay two-dimensional with Frank Gore as a threat out of the backfield, they should have some success moving the chains. With Mike Jenkins, Terence Newman and Orlando Scandrick all potentially out, there won't be anyone to match up with Braylon Edwards. And then there's Vernon Davis going over the middle of the field.
If, however, San Francisco falls behind, the Dallas pass rush will be able to tee off Smith. I don't trust San Francisco's offensive line to block DeMarcus Ware, Anthony Spencer and Jay Ratliff in long-yardage situations.
