Not much of a surprise here. The Falcons have said all along they want to keep Peterson, who has spent the past two seasons with the team. The move solidifies the linebacking corps, a day after Stephen Nicholas also agreed to terms.
Peterson and rookie Sean Weatherspoon were the primary starters on the outside last season. Nicholas played a backup role, after starting the previous season. Curtis Lofton is set in the middle and the Falcons added Akeem Dent in the draft. The Falcons also have a dependable backup and special-teams player in Coy Wire.
Peterson is likely to remain a starter in the short term. But, if there are any signs of him slowing down, Nicholas and Dent could have a shot at a starting job.
