More than 200 of his players went on to play in the National Football League, American Football League, and Canadian Football League, respectively. Robinson coached three AFL players who would later be inducted to the Pro Football Hall of Fame: the Kansas City Chiefs' Buck Buchanan; the Oakland Raiders' Willie Brown; and the Houston Oilers' Charlie Joiner. Robinson also coached James Harris, who with the AFL's Buffalo Bills became the first black quarterback in modern Pro Football history to start at that position in a season opener. He also coached Packers defensive end and Hall of Famer Willie Davis and the Super Bowl XXII MVP, Redskins quarterback Doug Williams, who would ultimately succeed Robinson as Grambling's head coach in 1998.
