It's a perfectly logical desicion. CC is in a crisis and he should give him one of the most dangerous strikers in mma? Where's the sense in that? Plus Mirko didn't know about it, so I can't believe people would deduce from this post that he is a coward. Although I wouldn't mind seeing them fight if mirko gets back on the track.
