Kenneth Lee Stills Sr. (born September 6, 1963) is a former American football safety in the National Football League. He is the father of American football wide receiver Kenny Stills. Stills was originally drafted by the Green Bay Packers in the eighth round of the 1985 NFL Draft. He played college football at Wisconsin. His first start in the NFL came against the Chicago Bears, the Packers' most hated rivals during the 1980s, and he memorably cost his team a 15-yard penalty for shoving Matt Suhey at the line of scrimmage. Stills also played for the Minnesota Vikings for one season before retiring.
