The question of who is the Greatest of All Time is one of the most discussed topics in MMA. But no matter who is debating the point, the same names populate the top of the list: Anderson Silva, Demetrious Johnson, Georges St-Pierre, and Jon Jones. Some people favor other fighters beyond those four and as time wages on, more will join their company but currently, the discussion of GOAT cannot be held without at least mentioning those four fighters, but perhaps the most undeniable of the group argues that the conversation is meaningless anyway.
