yes. Im pretty confident he would beat all of them in his prime years. Mir easy Gonzaga easy his victory over mirko was a fluke of a win really kongo not as good a striker and not good anywhere else JDS not proven as good a striker advantage cro-cop
He beats all of them more often than not including JDS. He gave him a real good go even past his best people forget this.
You have to think that JDS was not in his prime either when he fought Crocop. JDS has improved a lot since that fight.
Mir - Win. Mir has never had the greatest chin. I think Crocop would KO him. JDS - Not sure. I would favor JDS slightly Kongo - Win Gonzaga - Probably win, unless he gets kicked in the head again. The fight with Gonzaga was pretty close to Crocop's prime, probably 1 1/2 years after he won the Grand Prix
Yes CroCop would have won against them. He would have won against JDS, and have fought far better strikers than JDS. UFC CroCop was more like current day past his prime Rizzo. Both near champions in their promotion, both past their prime but both still very good fighters.
