Second choice.
First match : Fujita. Well.. do we need and explanation to this ?
Second match : Wanderlei Silva. That was in special rules, and for a lot of people (me inclured) Wanderlei murdered Cro cop (with zero experience).
Rematch ? Cro cop was using kicks, and boum head kick. He was MUCH LARGER, and with experience this time. Let's not forget that Wanderlei has takedown Cro cop in the first match lol.
Third match : Kevin Randleman. Cro cop was leading, and boum left cross it's over. this is what i call a lucky punch.
Rematch ? done in under 50 sec. Cro cop took no risk this time, he knows the power of Randleman.
Fourth match : Gabriel Gonzaga. If i recall, Gonzaga was tipped as the "next legend" in UFC HW before getting attached to the cage by Couture. Cro cop was confiant, left kick in preparation, and BOUM. fight over
Rematch ? : Cro cop know that Gonzaga has a weak cardio. He let Gonzaga run out of gas.. and bam elbow of death
There also the two win over Josh Barnett. But it's really the only occurence where i call it a real win
