Browns don't have cheerleaders.
Okay quasi cheerleaders don't count I guess, still the only team with 6 trophies which in my humble opinion is the true measure.

Cleveland Browns Cheerleaders Skirting the Issue
While the Browns have never had an official group, they have had cheerleaders on the sidelines during home games. In years past, this took the form of cheer squads from local high schools.
During the 1940s, the Browns even had an all-girl marching band. In the picture above, you can see team founder Arthur B. McBride having a little fun with the leggy girls from the 1947 squad.
