Cro Cop is completely overrated in an octagon. The ring was and always will be his domain.
In the ring he managed to beat guys like Peter Aerts, Jerome Le Banner, Mike Bernardo, Musashi, Mark Hunt, Remy Bonjasky, Ray Sefo, Barnett, Randleman, Mark Coleman and Wanderlei.
In the octagon he lost to Gonzaga, Kongo, Roy Nelson, a shitty looking Frank Mir and Brendan Schaub.
The KO was cool but it never would have happened if it was in a ring.
I understand that performances in general were not the same, but I don't see how that effects someone landing a HK on him.
