The Baltimore Ravens suffered through a historically poor rushing attack in 2013, with Ray Rice and Bernard Pierce rivaling Willis McGahee and Trent Richardson as the least effective tailbacks in the league.
Coach John Harbaugh is determined not to let it happen again.
"I think the whole thing just needs an overhaul," Harbaugh said last week, via The Baltimore Sun. "It was (myriad) things. We didn't block people well. We didn't move people. We didn't get on people. ... Our backs both weren't 100 percent and they didn't make enough guys miss, didn't break enough tackles."
Even though Rice and Pierce are just a year removed from forming a potent tandem attack that ultimately delivered a Lombardi Trophy, Harbaugh said the organization will look to add more backs in free agency or the 2014 NFL Draft.
Beyond mining for developmental projects late in the draft and picking up unheralded street free agents, Harbaugh's Ravens never have gone more than two-deep with quality running backs on the depth chart.
With Rice facing possible league discipline for his Atlantic City arrest and Pierce recovering from shoulder surgery, that might change this offseason.
