He thinks he was great but it just doesn't matter to him anymore. That is just a part of his past. It's not confusing.
I see his point, but deep down he probably doesn't think they are garbage. Before he flipped his WBA belt, he took dust off the I think IBF belt. I think he cares about his belts.
They turned him into something, and brought certain people to him that was bad for his psych and well being...
What Tyson is saying is theres more to his life now than boxing. Priorities change when you have kids, wife and then obviously Tyson lost a child, which is awful. Things happen. Long time ago they meant something to him, it's history and like Tyson said not long ago people will always remember him as the most ruthless fighter that has ever lived. Tyson's life and mentality has changed, that's all he's saying.
