Daniel Cormier was a little too comfortable in his rematch against Jon Jones.

Jones handed Cormier his first-career loss at UFC 182, but Cormier was eager to get his revenge when they ran things back in a title-fight rematch at UFC 214. He came in with a different kind of confidence after he captured the vacant belt with a finish of Anthony Johnson, followed by two title defenses.

This time, Cormier was the defending champion. He felt he had his arch rival figured out, winning Round 2 on two of the judges’ scorecards. However, he wound up getting knocked out by a head kick in Round 3 – a result which was later overturned to a no contest after Jones tested positive for a turinabol metabolite.

Looking back at the fight, Cormier thinks he may have been too loose.

“In terms of one (regret), it was the Jon Jones fight the second time,” Cormier said in an interview with Josh Thomson. “I was in shape, we were fighting, I was fighting really well, and then he kicked me in the body, right? I was like, ‘OK.’ Then he tried to head kick me and I was like, ‘Nope!’ I started feeling so good that I lost focus. Because now I’m being arrogant, talking to him, doing all those things when that never was me. I was always so locked in. That’s why I was so good. I could wrestle, and I could push a very high pace, but I was always so f*cking locked in.

“When I was in there, bro, it was like tunnel vision. I didn’t see anything. In between rounds, I would go to Bob (Cook) and Javier (Mendez) and say, ‘Did I win that round?’ They’d be like, ‘You were on top of him for four minutes, how could you not know?’ But I was so locked and focused, I didn’t even realize what was going on. But in that moment, I was talking sh*t to him, I’m pointing at him, I’m doing all kinds of stuff that just was not me, and then I got kicked in the head. If I could relive that, I would have stayed locked in and not taken my eye off the ball because he was just too good. I should have never did that.”

Cormier and Jones would never compete in a trilogy bout, but the now retired former UFC dual-champion said in the same interview that he’d be willing to wrestle Jones for RAF.
