Fran TarkentonPro Football Hall of Fame, Class of 1986

The orthodoxy of professional football in the early 1960s held that a quarterback's job began and ended inside the pocket. Drop back, read the coverage, deliver the ball on time, and trust the five men in front of you. A quarterback who left that pocket had, by the standards of the day, already failed at his job.

Tarkenton did not fit the mould, and by his own account the scrambling grew out of necessity rather than showmanship. He was not the biggest, the strongest or the fastest player on the field, and the Pro Football Hall of Fame describes his evasive style as something borne out of self-preservation. When the protection broke down, he simply kept the play alive, reversing field, buying seconds, and waiting for a receiver to come uncovered downfield. Defenders who chased him spent whole afternoons running in circles.

What made it more than a novelty was that it worked, repeatedly, for eighteen years. The scramble was not an escape hatch from the offence; it was part of the offence. He finished his career with 3,674 rushing yards and 32 rushing touchdowns, and he rushed for at least one touchdown in fifteen different seasons. At the time he retired, no quarterback in NFL history had run for more yards.

The durability matters as much as the highlight reel. A quarterback who leaves the pocket invites contact, and the conventional wisdom said that a player of Tarkenton's build could not survive that way. He played 246 regular-season games and missed only five of them to injury, which is the strongest argument available that his method was sound football rather than reckless improvisation. The modern quarterback who extends a broken play as a matter of routine is working from a template Tarkenton built first.

First stint · 1961–1966

The Vikings entered the NFL as an expansion team in 1961 and used a third-round pick that year on a quarterback from the University of Georgia. Minnesota opened its first season against the Chicago Bears on September 17, 1961, and Tarkenton came off the bench to complete 17 of 23 passes for 250 yards and four touchdowns, then scored a fifth on a three-yard rollout in the fourth quarter. The expansion Vikings won 37–13. It remains one of the most improbable debuts in league history, and it set the tone for everything that followed.

The six seasons that followed were the education of both a quarterback and a franchise. Minnesota was a young team still assembling talent, and Tarkenton spent much of that period keeping plays and games alive with the improvisation that would define him. He made his first Pro Bowls in this stretch, but the roster around him was not yet good enough to contend, and his relationship with head coach Norm Van Brocklin, himself a former quarterback of the classic pocket school, grew increasingly difficult.

New York Giants · 1967–1971

In 1967 the Vikings traded him to the New York Giants, and he spent five seasons there. The Giants years kept his production high but never delivered the thing he most wanted: New York did not reach the postseason during his time with the club. What those seasons did do was leave no doubt about his individual quality, and they left Minnesota with a problem it eventually decided to solve by paying to undo its own trade.

Second stint · 1972–1978

Minnesota reacquired him before the 1972 season, sending three players and two high draft choices to New York to bring him back. This time the supporting cast was waiting for him. The Purple People Eaters defence was at its peak, Bud Grant's teams were built to control games, and Tarkenton at last had a roster capable of playing into January.

The results came almost immediately. Across this second stint the Vikings won six division titles, reached three Super Bowls in a four-year span, and in 1975 Tarkenton produced the finest individual season of his career. He played his final game after the 1978 season, retiring at 38 as the most productive passer the sport had produced.
