According to Wikipedia, Forrest Griffin has competed against top competitors such as his win over Mauricio "Shogun" Rua, a unanimous decision over Quinton "Rampage" Jackson, and his controversial loss to Tito Ortiz. Griffin also won his UFC contract by a loss in the Ultimate Fighter finale to Stephen Bonnar, the first and only time such an exception has been made. Griffin's future MMA plans are unknown at this time, but he should not be discouraged by his loss to possibly the best fighter in the world. - Keith Koons, Associated Content
