I think it has a lot to do with the fact that a lot of them have day-jobs to go with their athletic careers. Once the sport becomes big enough that they all become full-time athletes and make tons of money in the process, they'll be more like other athletes.

I love listening to UFC fighters on the Opie & Anthony (SirusXM radio show). They're all very down to earth and likeable. I just hope money doesn't go to their heads in the future and start getting the NFL/Actor/Musician mentalities
