[1] Outside of playing football at Jackson State, he was also a sprinting champion in college, with a best time of 9.3 seconds in the 100 yard dash.

[2] After appearing in only two games during his rookie season, Jackson was traded to the Philadelphia Eagles along with defensive end John Zook for running back Israel Lang on July 7, 1969.

Jackson led the NFL in receiving touchdowns in 1973 with 13 and helped the Rams rebound from a 6–7–1 record the previous season to a 12–2 finish that won them the first of 7 straight NFC West Division Championships.

Alongside Stanley Morgan, Jackson helped form one of the NFL's best starting wide receiver duos of the late 1970s and early 1980s.

Despite this, Jackson was not one of the wide receivers selected to the NFL's All-Decade Team for the 1970s and he has yet to be elected to the Pro Football Hall of Fame.

[10] After retiring from professional football, Jackson coached receivers for 10 years in the NFL with New England (1985–89), Tampa Bay (1992–93) and New Orleans (1997–99).

In his first NFL season as a coach, the Patriots won the AFC Championship and played in Super Bowl XX.
