Re: G.George,Thez,Hogan,Austin-4 men with most impact on pro-wrestling?
Nature Boy Buddy Rogers for starting the trend of cocky heel, strut and all other than starting the "flying" moves incl. sending your opponent to the ropes preparing a slam or clothesline which is so commonly used today.
The Original Sheik for popularizing the trend of foreign heel which ruled wrestling trends for ages after him.
There are many more guys who had really huge impact on pro-wrestling who needs to/can be included in the list.
