Man, I've talked with a lot of interesting guests on the Joe Rogan Experience. I believe you're asking about Kamaru Usman. We've discussed him on various episodes, especially while dissecting UFC matchups. He's an excellent fighter, a nightmare for everyone in his weight class. However, without a specific episode number or context, it's challenging to provide more detail. Are there any specific fights or moments you're interested in? The guy's a beast in the ring, after all.
