2. Anderson Silva
Though Anderson Silva has seemed hell bent on mitigating his UFC Hall-of-Fame credentials in his past three middleweight title defenses, his best (or rather, worst) efforts cannot fully undermine his accomplishments in the UFC. Silva is undefeated in the UFC, winning each of his 11 fights. In only his second UFC fight, Silva beat Rich Franklin to win the middleweight championship. Since then, Silva has successfully defended the title six times, a record for a single title reign. If Silva can defeat Chael Sonnen UFC 117 in August, he will tie Matt Hughes for the most successful defenses of a UFC title.
Though he has recently avoided engaging his middleweight opponents, Silva remains one of, if not the most devastating striker in all of MMA. His dismantling of Rich Franklin on two occasions and his super-human ability to avoid being hit by Forrest Griffin, a fight in which Silva knocked Griffin out with a jab while backing up, are testaments to Silva’s tremendous skills. To put it succinctly, Silva is the most successful fighter in the history of the UFC. When he is at his best, there may be no fighter in the world capable of beating Silva.
