Daniel Cormier's professional debut at this past weekend's "Strikeforce Challengers" event was successful - even it wasn't pretty.

But no one is going to be more critical of the fighter than Cormier himself, who on Monday joined MMAjunkie.com Radio to discuss his Showtime-televised win over fellow MMA newcomer Gary Frazier.

"I've got to learn this sport," the former U.S. Olympian joked. "I really have no idea what I'm doing."
