10. Shane Douglas
"Without Shane Douglas, there would have been no ECW." That's a quote straight from WWE.com. It's even right at the very top of the Shane Douglas wikipedia page. Douglas is often credited (along with Paul Heyman, of course) as the guy who helped create ECW after an angle in 1994 where he won the NWA World Heavyweight Championship. After winning the title, he threw down the NWA belt to create the ECW Heavyweight Championship. The Company changed the meaning of its initials to Extreme Championship Wrestling and the "real" ECW was born. As "The Franchise" he played an integral part in making ECW a force to be reckoned with. In 1995 he left for WWF, changing his name to Dean Douglas and adopting a college dean gimmick. This was 1995 WWF after all. After a decent start his career never really took off, and by 1996 he was back in ECW. If you're wondering why, we got two words for ya: Shawn Michaels. Michaels and the Kliq (Scott Hall, Kevin Nash, Triple H, and X-Pac) were apparently not fans of Douglas at all, and spent a lot of time bad-mouthing him to Vince McMahon. Michaels even refused to drop his Intercontinental Championship to Douglas, instead vacating it so that Douglas would lose the title just minutes after getting it. Either Vince had so much trust in the Kliq that he changed his mind on Douglas, or he was on the fence to begin with and let the group convince him. Either way, Douglas was let go, never truly getting the chance to show what he could do in a major company.
