Junior Dos Santos vs. Cain Velasquez: What's Went Right for Cain Velasquez

UFC 155 played host to a heavyweight championship matchup between Junior dos Santos and Cain Velasquez. It was a rematch from last year's match when dos Santos knocked out Velasquez to win the title.

The rematch was far different than the first fight.

Instead of a 64-second knockout, we got a dominating performance from Velasquez. He utilized his vastly superior conditioning and wrestling to control dos Santos for a majority of the fight.

In the end, Velasquez regained his title. It looked like a vintage Velasquez performance. 

He was aggressive, relentless and masterful. His striking looked more refined than usual and his wrestling was as good as it usually is. 

He never let up. He never let dos Santos gain breathing room. He was JDS' shadow, as wherever the champ went, Velasquez was right there.

Fans seemed to be split on who would win this fight. Velasquez put no doubt in anybody's mind as to who is the best heavyweight in the world. 

Of course, you can talk about how good his striking and wrestling looked, but one thing is certain. Velasquez's pace and cardio was vastly superior than that of JDS.

He was frantic and never took his foot off the gas pedal. You could tell halfway through the first round that JDS was getting tired and Velasquez far from hitting his peak.

In the end, that was likely the determining factor in why Velasquez was so successful. When JDS was fresh, he was thwarting takedowns left and right.

When he hit a wall, Velasquez made him pay.

Velasquez needs to use this momentum as he may have a dangerous adversary on the horizon. If Alistair Overeem gets the next title shot, that will be a completely different animal to deal with.
