As Larry Wilson’s legendary career neared its end in the late 1960s, the St. Louis Cardinals’ secondary urgently needed a new core leader. They found their solution in spring 1969, effectively bridging generations. Roger Wehrli, a consensus All-American and Big Eight Defensive Player of the Year from the University of Missouri, completely changed the way individual pass coverage was viewed. Initially expected to be picked in the second round by some analysts, he defied scouting expectations at the combine by running a rapid 4.5-second 40-yard dash. This exceptional display of speed catapulted him into the first round as the 19th overall pick—a choice that quickly silenced critics and redefined NFL passing strategies for the next fourteen years.
Wehrli was an outstanding fluid mover, combining extraordinary recovery speed with a PhD in spatial trail technique. Unlike the physical, bump-and-run cornerbacks of his time who depended on boundary positioning, he demonstrated a highly poised diagnostic ability, matching the top route runners without giving up cushion. His quick closing burst enabled him to undercut routes with precision, turning deep threats into dead zones. His technical discipline was enhanced by excellent ball-tracking skills, making him a prolific playmaker who collected loose footballs, with 40 career interceptions and 22 fumble recoveries. Roger Staubach famously called Wehrli a "shutdown corner,” highlighting his complete containment of elite wide receivers and shaping new terminology for scouts.
His debut in the professional ranks in 1969 immediately demonstrated his dominance in his position. Wehrli joined the starting lineup, secured his side of the field, intercepted three passes, and earned consensus All-Rookie honors, finishing as the runner-up for NFL Defensive Rookie of the Year. He carried this momentum into 1970, posting a remarkable statistical season with 6 interceptions, which earned him his first of seven career Pro Bowl selections and his first first-team All-Pro recognition.
After a brief transitional phase for the Cardinals’ defense in the early 1970s, Wehrli fully established himself as an unstoppable perimeter defender by the mid-1970s. His exceptional coverage skills drew praise from Dallas Cowboys legend Roger Staubach, who famously called Wehrli a "shutdown corner"—a phrase widely regarded by football historians as the first time it was used to describe a defensive back. With this recognition from his toughest rival, Wehrli became a key player for Don Coryell's competitive St. Louis teams, earning four straight Pro Bowl selections (1973–1976) and three consecutive first-team All-Pro honors (1974–1976). His peak performance came in 1975, when he intercepted six passes, helping the Cardinals finish with an 11-3 record and win the NFC East.
As Wehrli’s career neared its end, his exceptional technical skills kept him highly effective, despite a natural decline in his elite vertical speed. In 1979, he earned his final Pro Bowl selection as a veteran and continued mentoring an evolving secondary. His long, historic stint in a St. Louis uniform concluded after the strike-shortened 1982 season, when he retired after 193 regular-season games, never having worn another professional jersey.
Wehrli was named to the NFL 1970s All-Decade Team, and in 2007, he was enshrined in the Pro Football Hall of Fame. That same year, Wehrli was part of the inaugural Cardinals Ring of Honor Class.
