6. Kevin Nash
The creator of the NWO. The man who snapped the streak of Goldberg. The man who lobbied for Hulk Hogan to turn heel. All of these statements connect to Kevin Nash, one of the smartest businessmen in WCW. Actually, Nash was a great performer in the ring as well. When Kevin defected to WCW, he created his own legacy. Yes, he had much success in WWE as Diesel, but Nash will always be remembered for the antics and events that made WCW a show that was "must watch" every Monday Night. From the NWO to the NWO Wolfpack, Kevin Nash was always a main event caliber wrestler. His size and solid athleticism showed that he could wrestle and keep up with the best of them. Nash will always be in the top 10 when talking about guys who changed WCW for the better.
