He was part of both Ottawa's Grey Cup winning teams in 1968 and 1969, catching an important 70-yard TD pass in the 1968 game when the Rough Riders defeated the Calgary Stampeders 24–21. Because he signed his original contract as a 19-year-old minor, he played out his option. He played three years, registering 47, 32 and 56 receptions, while averaging 10 touchdowns per season.
In 1970, he was placed on the injured reserve list, after playing in 5 games. In 1971, he only played in three games because of injuries and was placed on the team's taxi squad.[1] Although he wasn't on the active roster when the Cowboys won Super Bowl VI, he still received a ring and a full share of the playoff bonuses.
In 1972, he asked the Cowboys to trade him, so he was sent to the New Orleans Saints in exchange for second round draft choice (#39-John Babinecz).
New Orleans Saints
In 1972, he was acquired after he impressed the New Orleans Saints during a 1971 preseason game, where he had 3 receptions for 138 yards and 2 touchdowns. He led the NFL in both kickoff returns with 1,020 yards and a 23.7 average, even though he played through an ankle injury.
Injuries also hampered his 1973 season with the New York Jets. He started 5 games, posting 6 receptions for 109 yards. After he injured his knee during the 1974 offseason, Adkins was placed on injured reserve and eventually released before the start of the 1975 season.[3]
