Step 1 : Introduction to the question "What do U.S. NFL football teams the Steelers, Packers and Giants have in common?"
...The U.S. NFL football team Detroit Lions added cheerleaders to their support staff in 2016. That left only a handful of teams without cheerleader squads: The Pittsburgh Steelers, the Green Bay Packers, the New York Giants, the Buffalo Bills, the Chicago Bears and the Cleveland Browns. There used to be a cheerleader squad on the sidelines during Bills games but that ended in 2014 when the cheerleaders sued the team. Competition for spots on a professional football's cheerleader squad is fierce. Cheerleaders, however, are not paid the outrageous salaries of the players; in fact, their salaries aren't even close.
