Derland Moore was born on October 7, 1951. He walked on at Oklahoma and became an All-American. New Orleans drafted him in the second round, 29th overall, in 1973, which made him the highest-drafted college walk-on in NFL history until fellow Sooner Baker Mayfield went first overall in 2018. He played nose tackle for the Saints for 13 seasons and set the team record with 169 games, playing under five permanent head coaches and three interim coaches. He led the Saints in sacks in 1980 and made the Pro Bowl in 1983. He finished with the New York Jets and retired in 1986. He is in the Saints Hall of Fame and the Missouri Sports Hall of Fame, made the Saints' 40th and 50th anniversary teams, and was named one of the Top 100 Sooners. He died on September 24, 2020.

Roberts, did not have a first-round pick, so Moore was the first player selected by the Saints."
