Frazier: Vikings need more depth at RB

Coach Leslie Frazier on the RB position: "We'll probably have to either bring in a veteran guy or draft someone to help us with Toby (Gerhart)," Frazier told CBSSports.com. "We want to have a third guy on our roster for sure, whether he's a guy that's only used in third-down situations or has the capability of being used in first- and second-down situations."
