Jefferson was a 6 ft 2 in (1.88 m), 195 lb (88 kg) receiver, who was nicknamed "Sweet Pea".
Pittsburgh Steelers Selected in the second round of the
1965 NFL draft, 18th overall, Jefferson spent his first five NFL seasons with the
Pittsburgh Steelers (1965–1969). Jefferson finished the 1969 season with a career-high 67 receptions for 1,079 yards and nine touchdowns, and became the first Steelers receiver to post back-to-back 1,000-yard seasons. In his five Steelers' seasons, Jefferson started 56 of the 65 regular season games in which he played, with 199 receptions for 3,671 yards (18.4 average) and 29 touchdowns. He was selected to the Pro Bowl in 1968 and 1969. He was named first-team All-Pro by the AP, NEA, UPI,
Pro Football Weekly, and the
New York Daily News in 1969. Jefferson was named to the
Pittsburgh Steelers Legends team in 2007, as one of the best 24 Steelers players from 1933 to 1970.
Baltimore Colts Despite being the Steelers' best offensive player, conflicts with head coach
Chuck Noll as the team's
player representative resulted in a trade to the
Baltimore Colts for
Willie Richardson and a
1971 fourth-round selection (104th overall–
Dwight White) in an exchange of receivers who had fallen out of favor with their old teams on August 20,
1970. With the Colts for only one season, Jefferson helped them reach and win
Super Bowl V. He finished the
1970 regular season with 44 receptions for 749 yards and seven touchdowns. and caught a 9-yard touchdown pass from Unitas while dragging a defender into the endzone. Jefferson had three receptions for 52 yards in the Colts 16–13 victory over the
Dallas Cowboys in the Super Bowl. After coming from the 1–13 Steelers in 1969, and winning the Super Bowl with the Colts in 1970, his one year with the Colts was his favorite season in the NFL.
Washington Redskins A contract dispute with the Colts ended with Jefferson being dealt along with ninth-round draft picks in
1973 (218th overall–
Rick Galbos) and
1974 (213th overall–traded to
Los Angeles Rams for
Joe Sweet) to the
Washington Redskins for
Cotton Speyrer and a 1973 first-rounder (25th overall–traded to
San Diego Chargers for
Marty Domres) on July 31, 1971. He spent six seasons with the Redskins under head coach
George Allen, helping them reach
Super Bowl VII in
1972, and retired after the
1976 season. In his first Washington season, he caught 47 passes (his high with the team), and was selected to play in the 1971 Pro Bowl. The AP and
Pro Football Weekly named Jefferson first-team All-Conference. In 2012, he was selected as one of the 80 greatest Washington players. ==After football==
