Lockhart was scouted by future
Pro Football Hall of Fame member
Emlen Tunnell for the New York Giants. Tunnell, who became the first black assistant coach in the NFL, scouted at smaller schools, especially
HBCU schools like North Texas. The Giants drafted Lockhart in the 13th round of the
1965 NFL draft, and Tunnell would become his first
defensive backs coach. Tunnell gave Lockhart the nickname Spider, because he could cover the field and receivers like a spider. Teammate
Brian Kelley said Lockhart had the speed at free safety to both run down receivers on passing plays, and race toward the line on running plays. The popular He was a
Pro Bowl free safety in 1966, despite the
1966 Giants having a 1–12–1 record, and being the worst defensive team in
points allowed/game in NFL history. The Giants allowed 501 points in 14 games for a 35.8 points per game average. (In 2024, the
Carolina Panthers allowed 534 points in 16 games; 33.4 points per game.) The Giants worst game came on November 27, 1966, a 72–41 loss to the
Washington Redskins. The Giants' run defense was shredded for 209 yards on only 24 attempts (8.7 yards per carry), including four rushing touchdowns. The Giants also gave up 132 net passing yards (on 16 passes, three for touchdowns). As of 2025, Washington's 72 points is still the most points scored by a team in a single game, and the teams' 113 combined points are the most total points in a single game. Lockhart did get an interception against future hall of fame quarterback
Sonny Jurgensen in the game. Despite being a Pro Bowl cornerback in 1966, he was switched to safety in 1967. From 1969-75, he started 89 of the 91 games in which he appeared for the Giants, with 18 interceptions and eight fumble recoveries. Over his Giants' career, Lockhart intercepted 41 passes and recovered 16 fumbles during his 145 games played. Lockhart also gained 328 yards returning punts and was famous for rarely calling for a fair catch. == Post-football life ==
