6. Philadelphia Eagles

The Eagles' cheerleader site is the only one in the league that, before entering, displays a button warning you of "mature content." The Eagles continue to be among the most aggressive cheerleading squads. The team was the first team to launch a swimsuit calendar app this year (cost $1.99 on the Android), it encouraged fans to “Celebrate the Holidays with the Cheerleaders,” and members of the squad maintain a robust blog.

The squad has engaged in a number of activities, including a trip to the U.S. Military installation Camp Buehring in Northern Kuwait. This year, the cheerleaders will be performing at the Senior Bowl, one of the league’s premiere pre-draft events.
