Source: WWE: Clash of The Champions 11-15-189- Ric Flair vs Terry Funk- I Quit Match
One of the things that I always respected about The Nature Boy Ric Flair the pro wrestler is that he always took on the best. At least the best that was available to take on at the time. One of his famous lines was that "to be the man, you have to beat the man". And then you would say something like "and pal you aint it". But the first part was dead on and that is how he approached pro wrestling whether he was a contender the the World Champion. The only thing he was interested in was being the best in the pro wrestling business.
Terry Funk is the perfect example of Ric Flair's style as a pro wrestler as far as who he took on. Because when Funk was wrestling full-time in America and his head was right, he was one of the best to the point he was NWA World Heavyweight Champion at one point. He might of even beaten Ric Flair for his title. And they had a great rivalry in the 1980s. Funk was essentially a great street fighter who was big and strong and took incredible risks physically as a pro wrestler that his body paid a heavy price for and still pays that price, but he was also a great pro wrestler.
