Olympian Daniel Cormier sits undefeated with a flawless 12-0 record, and in 2012, the AKA member won the Strikeforce heavyweight Grand Prix by dominating former UFC champion Josh Barnett in exciting fashion.
2013 has been kind to Cormier, as the wrestler picked up a win on the final Strikeforce card as well as a win over Frank Mir in his UFC debut.
So why is he on our list?
Cormier may have shut out Mir back in April, but he hardly impressed anyone with his method of attack. All three rounds saw the Strikeforce stud hold Mir against the cage and stall for time between body punches. Continually through the bout, referee Herb Dean restarted the fighters in the center of the Octagon due to lack of action.
This sleepy performance was addressed by Cormier, who told MMAjunkie.com that he was displeased with his fight.
... But man, I was nervous. I felt so nervous. It's almost like you want it so bad and you want to do so well, and then you just kind of lay an egg a little bit. I didn't fight the fight I wanted to.
Cormier's standing in the rankings has improved, but by putting on such a boring showing in the co-main event of a card that aired on national television, he hurt his marketability in a major way.
