Well they are technically cheerleaders. But they do no stunts jump or tumbling. They are more there just for the men that come to the game and watch it. All they really do is shake there hips

Yes, they dance a lot because they are on the hard ground and can't risk getting hurt. They do the same as high school cheer leading. They do stunts if you look closely.

NFL stands for National Football League. The cheerleaders cheer the football players on but I believe they may be part of the organization

Yup. Watch carefully at a few games.

Yes, what would make you think there wasn't?

Yes, there are.
