Recently, 49ers general manager Trent Baalke explained that the 49ers' future at running back, ideally, does not include one player, such as Frank Gore, on the field for nearly every snap.
"I'm a big believer -- we are big believers -- in a three-headed approach," Baalke said. "In other words, having a group of backs that bring to the table something a little bit different than the other one so you can do a lot of different things. But also having those backs be able to do enough things the same so you don't become so predictable on game day."
In other words, Kendall Hunter and LaMichael James will be involved in 2013. Don't expect a huge workload for Gore, though he's still the clear RB1 in San Francisco.
