Productive base end with good play strength who continues to add weight to his frame. Roberts has chalked up stats as a standing defender but isn’t athletic enough to play as a 3-4 outside ‘backer in the NFL and might not have the brutality to play inside at three-technique despite his size. Roberts won’t win the rush with speed or quickness but he can collapse the pocket with a finesse-to-power rush transition. He is slow to read and react to mesh points and counters. He’s also a wildly inconsistent arm tackler. The production could earn him an opportunity, but it might not be translatable as a base defensive end in the pros.
