I had a similar experience to yours. I used to do MMA and got fairly good. I’ve trained with people who fought locally in the ring and did ok with them in sparring matches. They were clearly better but I did ok against them. One day I ended up sparring with someone who eventually went on to become a semi finalist in the Ultimate Fighter. It was like I was 5 years old fighting a college student. I could do nothing against him. He completely destroyed me. He didn’t have a successful UFC career. I can’t imagine what it would be like to fight a top tier pro.
