As was his teammate on the Green Bay Packers and fellow member of the NFL Hall of Fame Jim Ringo, Robinson was born in New Jersey.
The linebacker was selected by three football leagues in the 1963 draft – in the first round with the 14th overall pick by the Green Bay Packers (NFL) and by the San Diego Chargers of the AFL in round three with the 17th overall selection.
Not only that, Robinson was also selected by the Montreal Alouettes of the CFL (Canadian Football League).
Robinson played the first 10 seasons of his career with the Green Bay Packers, and his final two for the Washington Redskins.
