He didn't say that straight after the fight, and not really, it's more of just the reality. It's the equivalent of saying he caught me with a lucky punch, it wasn't just luck, it was skill, but was some luck in the fact that it hit him in that exact place and all the circumstances combing together to give Ruiz more of a chance. He gave Ruiz a lot of credit. It's incomparable to the litany of excuses Wilder has made, ring costume being heavy, trainer disloyalty, the ref etc. The ring walk costume which is his main excuse is the legit the worst ever excuse I've heard.
