Who's the greatest MMA fighter of all time?

Fedor Emelianenko. His only loss was a complete sham. Google it, you'll see. After Kevin Randleman slammed him straight onto the top of his head, and Fedor just rolled out and submitted him. My mind was made up. I can't wait until the UFC signs him.

Right on his heels though is Anderson Silva. World class in all aspects of the game. Think the UFC will ever have an open weight tournament like Pride did back in the day. That would be sick.
