Each team is very different so it's hard to determin who is the best overall team in the NFL. The DCC I think are the most well known team, with a huge fan following highly due to this show. However a lot of other teams have huge fan followings which would be hard to say which group of fans are stronger.
The Texans are huge on social media which helps give them lots of attention and helps make them highly popular so if it's based purely on popularity as to who is the best in the NFL then they would be top competitors. I wouldn't ever say they are as strong dancers though, they are good dancers but I find the DCC have a lot more time put into all the dances and the skills within the girls they choose.
The Dolphins, Seagals, Broncos and Colts also all have very huge followings with the fans and I would say would be competitors for the title of one of the best teams in the NFL.
A lot of the teams reference themselves as the best in the NFL and I think it depends what you consider personally as the best. No two teams within the NFL are the same, some have very high dance skills and some not as high a standard (my opinion), some do an incredible amount of charitable work while some do very little, some are incredible with the fans in all aspects while others only interact at games or specialised events not using any social media platforms (which I find makes fans like them more as they can actually interact with them no matter where in the world they are from). So it depends what you think would make the team the best in the NFL.
I dont think any teams are quite at the same standard as DCC are but I think having the TV show makes them have a high standard as everyone is watching and judging them. They have a lot they have to offer to fans and to get their attention and they have to make the team perfect.
Sorry this is kinda long but I guess not many people are aware of the differences in the teams or know much at all about the other teams, but i like all of them in different ways. So thought I'd share my option of them a little bit. (I probably could keep going for hours about them all as no one ever wants to talk NFL Cheerleadrs with me.)
