The Facts: OC Geep Chryst has no idea how the 49ers will ultimately attempt to replace running back Frank Gore, who was the main man in the team’s backfield for nearly all of his 10-year run with the franchise. “That’s what we need camp to find out,” Chryst said.

Diehards Line:Carlos Hyde will get an opportunity to be the featured back, but Chryst said he does not want tightly defined roles. He wants Hyde, Reggie Bush, Kendall Hunter and Mike Davis to be able to thrive in different roles. “We feel there’s real nice depth there,” he said. “Now we got to work on rounding out anybody’s game. ..." Fantasy owners will want to watch this one closely before investing too heavily in Hyde. We'll definitely follow up in coming weeks.
