And I only want to talk about his action inside the cage & related to it without bringing anything that happened in his personal life. 1. His dope violation. In contact sports, where it matters most, it almost delegitimize his entire career. 2. His questionable Resume: Apart from DC or may be Gus you can't argue that his resume is really strong. No doubt its name heavy but those names were at the end of their career or out of their prime. 3. 3 questionable wins : His wins against Gus 1, Santos & Reyes are really questionable & can argued that he lost all of them. And that is too much for someone to be called GOAT. These should be too much for anyone without any bias to consider him as GOAT.
