Valero wasn't looking for the knockout against DeMarco; he was boxing, and boxing very cautiously for his standards. And he still outboxed and stopped DeMarco, who was a skilled and up-and-coming contender.
Doesn't explain why he would knock Gatti out in 4 rounds though. And he clocked Valero with many hard shots in that fight, hardly a testament to his fabled one punch knockout power.
Edwin was a powerful accumulation puncher not a true 1 shot Guy. Arturo would never know when to quit and could literally be killed by the beatdown as in Mancini vs Kim. I see 12th round Tko win for Inca then Arturo tragically lapsing into a coma while in the hospital.
YES THIS IS AN OLD VID BUT THE STORYS ARE TRUE ABOUT HOW GOOD AND HOW HARD HE HIT.. vALERO BUILT UP A REP FOR PUTTING A HURTIN ON WORLD CLASS FIGHTERS OUT HERE IN THE SO CAL GYMS.... hAVING TO WEAR HUGE GLOVES AND STILL DAZING AND HURTING GUYS. juST CAUSE HE DIDNT KO dEMARCO REAL FAST DIDNT MEAN HE WAS A KO ARTIST... i MEAN EVEN ATG PUNCHERS LIKE hERNS,lOUIS,fOREMAN,aRGUELLO CAME ACROSS OPPONENTS THAT JUST WERENT GETTING KOD THAT NIGHT... mAKE NO MISTAKE dEMARCO JUST HAD A TOUGH AS CHIN AND CAME IN CONDITION..... BESIDES vALERO IMPRESSED ME MORE IN THAT FIGHT BY DOMINATING A YOUNG REPSECTED CONTENDER , THAN HIS OTHER QUICK KOS..... hE SHOWED HE COULD WIN BOTH WAYS,...... WOuld have been a war but in the end valero would have put a serious hurting on Gatti.
