6. The UFC 229 Press Conference
McGregor is as famous for his trash talk as he is for his fighting. He has a remarkable way with words and is brilliant at mental warfare. The one thing is that he never loses control. However, the UFC 229 presser revealed his vulnerability. He was a total loose cannon.

Since the conference, he has admitted that he was actually drunk. McGregor targeted everything from Khabib’s father, to his religion to Russian geopolitics in a furious, venomous tirade. But it sounded unhinged in a way that fans had never seen before. It was seriously uncomfortable to watch.
