Who do you think is the best combat sports fighter of all time? It’s a question that a lot of people have tried to answer, but no one has come up with a solid answer. Part of the problem is that periods have come and gone since the emergence of cage fighting and the founding of the UFC. So how do you rate fighters who dominated for a period yet faced weaker competition in other promotions? Could one of today’s emerging stars, such as Chuck Liddell, Royce Gracie, Wanderlei Silva, or Kazushi Sakuraba, beat a dominant force like Chuck Liddell, Royce Gracie, Wanderlei Silva, or Kazushi Sakuraba in their prime?
