Ex: Imagine if Hearns never fought Leonard. Hearns fan boys would be saying how there's no way he loses to Leonard, let alone by TKO. He's too tall, too long, hits too hard. Ray Leonard can't take those shots. He can't bang with Hearns. He'll be running the whole time. etc.
That's why you have to actually fight, in order to test your greatness. Non of this fantasy land BS that Flowmos try and incorporate in their arguments.
