Defensive Backs

Experience: 18 years


Former NFL linebacker David Merritt, Sr. enters his first season with the team as an assistant coach in charge of the Arizona’s defensive backs after playing for the Cardinals for three years (1993-95). He joined the Cardinals staff on 2/14/18 after spending the last 14 years coaching with the New York Giants, including the past 12 seasons as the Giants secondary/safeties coach.

During his tenure with the Giants, Merritt was a part of two Super Bowl winning teams (XLII, XLVI) and helped New York reach the postseason six times. He tutored S Landon Collins the past three seasons and helped Collins get selected to two Pro Bowls (2016-17) and be named first-team All-Pro in 2016. Collins led the Giants in tackles in each of the past three seasons (2015-17) to go along with eight INTs, four sacks, three fumble recoveries and two forced fumbles. In 2016, Collins had a career-high 125 tackles, the most in team history by a safety. He also became the only player in NFL history to have 100 or more solo tackles and at least two sacks, five INTs and 12 passes defensed in a season. Collins was a two-time NFC Defensive Player of the Week and the NFC Defensive Player of the Month in November.
