#2 Forrest Griffin
Forrest Griffin is one of the most loved fighters in the UFC history. His fight with Stephan Bonnar at the Ultimate Fighter 1 Finale was a crucial milestone for the promotion.
And this is probably why everyone had high expectations when Griffin won the Light Heavyweight championship at UFC 86 by defeating Quinton Jackson.

Griffin’s win came via a unanimous decision after a five-round war with Jackson. It was one of the best fights of 2008 as both fighters were equally matched.
Griffin, however, lost the championship just five months later in his first defence when he was knocked out by Rashad Evans at UFC 92. He never got near the championship again and five fights after his defeat to Evans, Griffin decided to step away from the octagon.
