Is this a real thread?
Let me help you out....http://www.bjpenn.com/mmanews/5-shocking-facts-about-the-ufc-pay-scale/
UFC fighters are paid like shit. If any UFC fighter could make it as an athlete in any other sport they would...but they can't.
Someone that makes more money than you, has more of a life than you, has better work ethic and more motivation than you, gets laid more than you, has more to wake up in the morning than you.. I could go on
Anthony Davis, one of the best athletes in the world gets KO'd stiff with just a glancing blow.
Any of the "C-Level" HW's in the UFC would KO him in 20 seconds.
That's a stretch. Most guys who fight aren't doing so because they can go pro. Most guys fight because they love to fight.
I don't think it is a stretch as it relates to the discussion about world class athletes. I agree that there are many fighters who are in it for the love of the sport, but I doubt there are many (if any) world class athletes fighting that have the athleticism to compete in another sport where the pay is exponentially better and choose to stay for the love of fighting.
