It's crazy to think that less than three years ago, Daniel Cormier hadn't even had his first professional MMA fight yet. Now on May 19, he'll fight Josh Barnett to crown the first and only Strikeforce Heavyweight Grand Prix Champion. Admittedly, Cormier will point out that time and experience are the great factors that led him to the belief that he can go toe to toe with former UFC heavyweight champion Josh Barnett and come away with the win. "I told this to Bob (Cook) the other day, I go if I have to fight Josh last year, I would have been so nervous like I'm not ready. But now I'm ready. Your career progresses, and there's no way to control that. The way to control that is by winning fights," said Cormier.
