Stephens-Howling gives the Steelers a dynamic third-down back and a core special teams player who proved himself to be a dangerous return man during his four seasons in Arizona. His role on offense will hinge on how effective the Steelers are at finding creative ways to use Stephens-Howling in the scheme.
The Steelers remain interested in free-agent Ahmad Bradshaw, according to Rapoport, but even if they don't sign the former New York Giants running back, the presence of Stephens-Howling could mean trouble for Baron Batch's third-string roster spot.
Pittsburgh isn't out of the woods. The Steelers still lack a foundation at running back, and we expect the team to look for help in the draft starting possibly with the 48th pick in the second round.
UPDATE: The Steelers further addressed their running back needs by selecting Michigan State's Le'Veon Bell with the 16th pick in the second round.
