6. Machida Rock's Captain America's Temple
Victim: Randy Couture
When: UFC 129, 4/30/2011
Lyoto Machida is a bad man, a real bad man. Randy Couture is an old man, a really old man. That was never more evident than in this bout that took place last year. Let this be a lesson to all, don't run into an oncoming Machida, it will end badly.
