The Steelers have decided that Jonathan Dwyer and Isaac Redman are complementary backs.
It's an easy self-evaluation for the Steelers' coaches. Given ample opportunities last year, Dwyer could only muster 3.99 YPC and two touchdowns while Redman was at 3.72 YPC. The Steelers are expected to select a running back in the second or third round of the draft, and could pair that rookie with a veteran free agent such as Ahmad Bradshaw or Beanie Wells. Dwyer will be a role player at best this season.
