Zahava I want to make some corrections to your post about cheerleaders.
The Patriots do have cheerleaders. Only 6/32 teams currently do not have cheerleaders.
Basketball has cheerleaders and dance squads. Only the San Antonio Spurs don’t have them and they got rid of them in 2018.
Hockey has cheerleaders. They are often in the crowd cheering and come onto the ice to remove excess snow.
Some Baseball teams have a dance/ cheer squad that throws tshirts and dances on the dugout during inning breaks. They are usually dressed more modestly. There are also teams that employ ball girls down the foul lines.
