In a relatively short period of time, the Steelers went from scrambling to find a cornerback who could play to believing they have two No. 1 cornerbacks. When they acquired the second of those No. 1 guys (Joe Haden), they moved the other (Artie Burns) from the left side to the right. Suddenly, the Steelers have the NFL's top pass defense. So, who has been the Steelers' best cornerback? The NFL's statistical service suggests it's Haden. Opponents are averaging a 5.83 yards on deep (15-plus yards) passes to the offense's right side of the field (the defense's left side, or Haden's domain) and 12.31 yards on deep passes to the defense's right side. The Steelers' defense is allowing a 27.8 completion percentage to its left side, 43.8 to the right.
