The product of LSU would lead his respective league in Interceptions twice (1966 AFL, 1970 NFL) and he would secure 57 picks overall in his career.
His best performance took place in Super Bowl IV where he helped the Chiefs win the game with a fumble recovery and an interception. Robinson actually had a pick in each of the three AFL Championship Games he played! Robinson was one of the early inductees into the Chiefs Hall of Fame, receiving the call in 1974.
He would finally enter the Pro Football Hall of Fame in 2019 as a Senior Candidate.
