If Evans is getting tossed trying to take him down, there's not a chance in hell Shogun brings Machida down.
Lyoto doesn't just win fights. He has never lost a round. This guy is the most mentally sharp fighter in the octagon, in any weight class. The only way "defensive" guys like Machida lose is when they let their guard down, but based on the previous statement, I doubt we'll see The Dragon taking a mental break in a fight any time soon. I really cannot see this guy losing a fight... I'm sure it'll happen at some point, but on paper, this guy will not lose a fight. He's just too good at what he does.
