I think there has to be a difference between wrestling and UFC as we all know what a farce the wrestling is. WWE was all about the show and you had to be brain dead to enjoy it and it shows with the audience it attracts. The difference is someone could get seriously hurt fighting out of their weight class and was the reason for weight classes in the fist place. Imagine someone punching another fighter who is half his weight. Good for the viewers I agree but it can't possibly be good for the sport long term as it will only be a matter of time before someone is killed.
