3. Chuck Liddell
Before Conor McGregor came along, the likes of ‘The Iceman’ and Randy Couture helped to make the UFC the world’s most popular MMA promotion. Liddell had a savage, relentless style that helped him to win the UFC light-heavyweight championship. However, he failed to evolve and when the losing streak started it all turned nasty. Liddell won one of his last six fights with the UFC. Even worse, four of those defeats were by knockout.
Then, after eight years on the sidelines, Oscar De La Hoya convinced the 48-year-old to return against the active Tito Ortiz. It was terrible to watch as Ortiz won by KO. Liddell looked old and it was grim viewing. Overall, ‘The Iceman’ stayed around too long and should never have returned for the sake of his own health. There were no winners from this event because it just left a bad taste.
