UNITY TWP., Pa — The Steelers running backs got to work on Tuesday and went straight for pass protection drills. Eddie Faulkner made the running backs work on their hand usage and physicality. While doing the drills, the running backs worked with tennis balls and on the sled. It was the first time they have done either at training camp, thus breaking new ground for the Steelers. Benny Snell returned to the field for the first down and went through the drills.
