One of the things Mike Tomlin and the Steelers' coaching staff loved about William Gay was that he not only knew his responsibilities as a cornerback, but he also knew what everyone else on the field was supposed to be doing. And he knew exactly what opponents were trying to exploit.
That's why once Ryan Shazier was lost last season, you'd often see Gay walk onto the field during timeouts to talk to teammates and give them a tip here or there that was gained from his 10 years in the league.
Cameron Sutton might not have Gay's experience. But he has quickly established a trust with his teammates and the coaching staff that he has the ability to assimilate things quickly and translate it onto the field. He showed that last year as a rookie, when he spent the first half of the season on injured reserve but returned in the second half and immediately helped the team deal with an injury to Joe Haden by stepping into the lineup and playing well.
