10. Stephan Bonnar
A star of the UFC boom in 2005, Stephan "The American Psycho" Bonnar was the face of MMA for a short spell. He made his name in one of the most vicious fights in UFC history, losing a judges decision to Forrest Griffin in a 3 round stand up battering. It was Bonnar's moment of glory, and the peak of his fame, his career was mixed and quickly got lost in the boom of new MMA stars. There was also steroid controversies, Bonnar would test positive for banned substances on Two occasions after fights, and he is now retired from the sport of MMA. Bonnar was a good athlete and physical brawler, but he could sell a fight too. He could certainly make the jump to WWE's athletic showmanship. He has a good voice for promos and a fearsome look, he could bring his "American Psycho" gimmick to WWE and have some success in the same vein as Ken Shamrock did. Could it happen? Well, earlier this year Dave Meltzer's Wrestling Observer did in fact report that Bonnar was interested in coming to work for WWE. Watch this space.
