I'm one of the last people that would try to take anything away from what Machida has already achieved, but this thread is full of lose.
To make the implication that Machida has achieved anything near what Anderson has in MMA yet is just ridiculous. MMA fans have a tendency to forget everything but a fighter's last fight; which simply doesn't work when comparing achievements.
Machida just won the title in his most recent fight and people are already comparing him to Silva who has recently broken the record for most consecutive wins in the UFC, it's obnoxious.
Someone also went on to state that they thought Anderson was ducking Lyoto, and then gave a list of points based on nothing more than unsupported speculation, and rumors which had no source.
Before we get ahead of ourselves, sit back and think about what you're trying to compare. Someone who just became champion in his last fight(has yet to defend the title), and someone who has been champion for years. He unified the Pride/UFC title and has beaten the majority of his opponents inside of two rounds. He also had a fight where he had 100% accuracy against another undefeated fighter.
