Man, that's a tough one. We've had so many incredible fighters and personalities from the world of MMA on the show. It's hard to remember all of them off the top of my head, you know? I’d suggest checking the JRE library on Spotify where you can look up your favorite MMA fighters and see if they've ever been on. I mean, I've had legends like Chuck Liddell, Georges St-Pierre, and Conor McGregor, plus loads of others. You can even filter by episode type to find the MMA shows quicker. So, I'd say it’s worth checking the JRE page on Spotify for the full list, man.
