Weekend mail call:Rory from San Francisco wants to know if I think Carlos Hyde or Marcus Lattimore will get first crack at taking carries away from Frank Gore.Bill Williamson: I'd think it's going to be Hyde. They used a premium pick on him, he was the 57th overall pick, and he's healthy. Latitmore is coming back from a major knee injury he suffered at South Carolina in 2012. I think the future is bright for Lattimore, but the 49ers will be cautious with him, So, I think Hyde will be given the first opportunity.
