Although he said the fight with Aldo would be over in a minute or two, he did once say the fight will be decided with the very first exchange and he was 100% right about it. It's pretty crazy how he was THAT accurate. It's the most perfect prediction ever.
It wasn't the first strike he threw, but him and Aldo exchanged and Conor put him down immediately, first exchange and it was over. Insane.
But yeah, he's got some predictions wrong because they weren't 100% accurate to what he said, but he still did finish all of his fights rather quickly. He's got a few wrong, but he's got most of them right. Not just his fights, but also some other predictions he's made that have to do with some other things have been right, too.
