It's official, we have signed RB Brian Westbrook to a one-year contract"
The 49ers tweeted the above earlier today, knocking one more running back off the dwindling "lone wolf" RBs. It's still unclear what Westbrook's role will be at this point. However, I would say it knocks down Gore's value a little bit, though not a lot. Depending on where you have Gore ranked I would say he might move down a spot or two.
In some ways, having Gore not take all the rushes might be a good thing for him, though inevitably he's going to lose a touchdown or two in the process.
