UFC 155 Results: Cain Velasquez & the Top 25 Pound-for-Pound Fighters in the UFC

On Saturday night, Cain Velasquez showed that the first fight with Junior dos Santos didn't mean as much as we all thought it did.

Velasquez completely dominated Dos Santos from bell to bell, earning scores of 50-45, 50-44 and 50-43. Velasquez was never in trouble at any point in the fight and was able to do whatever he wanted.

He will surely jump back to the top 10 pound-for-pound fighters. Let's find out where exactly he ends up.

No. 25: Chad Mendes

Chad Mendes is making a serious case for a rematch with Jose Aldo at some point in the near future.

Since suffering the loss to Aldo, Mendes has won two straight fights by first-round knockout, in a combined time of less than two-and-a-half minutes.

One win over a top-10 guy should earn Mendes another shot.

No. 24: Nate Diaz

Nate Diaz earned his title shot by decimating Takanori Gomi, Donald Cerrone and Jim Miller. He was expected to seriously challenge Benson Henderson, and the fans favored him to win the fight.

However, it did not go as many expected.

Diaz was outclassed throughout the fight as Henderson earned a clear-cut unanimous decision victory.

No. 23: Ian McCall

Ian McCall is almost universally considered the No. 3 flyweight in the world behind both Demetrious Johnson and Joseph Benavidez.

The UFC flyweight division is still relatively small, so McCall shouldn't be too many fights away from a title shot.

He may earn a shot if he beats Benavidez at UFC 156.

No. 22: Urijah Faber

At UFC 149, Urijah Faber dropped a unanimous decision (50-45, 49-46, 49-46) to the new interim bantamweight champion—Renan Barao.

Faber seemed to have no answer for anything Barao was doing, as Barao's kicks were able to keep Faber on the outside and spending most of his time defending.

Faber is undoubtedly the No. 3 bantamweight in the world, but with losses in his last five title fights, he just can't keep up with the best of the best in the division.

Faber will face Ivan Menjivar at UFC 157.

No. 21: Alexander Gustafsson

At UFC on Fox 5, Alexander Gustafsson earned his first undeniable top-10 victory. Gustafsson won a unanimous decision over Mauricio Rua and proved that he is a legitimate threat in the division.

It was said before the fight that it was for a No. 1 contender position, so we'll see if Gustafsson does really earn a shot at the winner of Jon Jones and Chael Sonnen.

No. 20: Chris Weidman

Chris Weidman can now be considered one of the top fighters in the UFC middleweight division—and the entire world.

Weidman is 9-0, 5-0 in the UFC, with wins over Demian Maia, Mark Munoz, Tom Lawlor and more.

Weidman is undoubtedly the No. 1 contender in the middleweight division, but an injury has forced him out for several months.

No. 19: Chael Sonnen

Chael Sonnen came into the fight at UFC 148 with everything to prove. He had a chance to dethrone the greatest fighter of all time and back up all of his trash talk.

For the first five minutes, he did just that, as he took down and controlled Anderson Silva. Then, in the second round, Silva did what he does best, as he used his pinpoint striking to finish Sonnen by TKO.

Sonnen is currently coaching on The Ultimate Fighter against Jon Jones, and the two will fight in April of 2013 for the light heavyweight title.

No. 18: Gray Maynard

The former lightweight title challenger, Gray Maynard, is almost universally considered to be a top-three lightweight in the world.

Maynard was last seen in action at UFC on FX 4, where he earned a unanimous decision over Clay Guida in a fight that saw Maynard, and not Guida, be the fan favorite.

Maynard was supposed to face Joe Lauzon at UFC 155, but an injury forced him out of the bout.

No. 17: Junior Dos Santos

At UFC 155, Junior dos Santos was looking to solidify his legacy in the heavyweight division. Another defense would have tied the record for most consecutive defenses.

Unfortunately, it was not to be, as Cain Velasquez decimated Dos Santos en route to a unanimous decision victory.

No. 16: Rashad Evans

Rashad Evans fell short in his title-reclaiming effort against Jon Jones, but he'll certainly be back to fight for the title again.

In the meantime, Evans is stuck in a Jon Fitch (pre-Johny Hendricks) type of situation, where he is one of the best fighters in the division but may have nothing to offer the champion.

His next fight will be against Antonio Rogerio Nogueira at UFC 156.

No. 15: Joseph Benavidez

Joseph Benavidez was the favorite coming into the fight, but that didn't matter in the end, as he dropped a split decision and did not win the inaugural UFC flyweight title.

It was a close, competitive fight, but in the end, the wrestling of Demetrious Johnson proved too much for Benavidez.

Benavidez will face off against Ian McCall at UFC 156.

No. 14: Lyoto Machida

Machida may have a losing record in his last five fights, but overall, he is No. 3 in the division and belongs on this list.

His last fight saw him knock out Ryan Bader and move his overall record to 17-3. Machida is set for a No. 1 contender fight with Dan Henderson at UFC 157.

No. 13: Carlos Condit

At UFC 154, Carlos Condit had a chance to dethrone GSP. He had a chance to unify the interim title and the undisputed title, and he almost did.

In the third round, he landed a solid head kick and almost finished GSP, but when all was said and done, GSP had his hand raised and had another unanimous decision victory.

Condit remains a top-five welterweight.

No. 12: Dan Henderson

At 42 years old, Dan Henderson is as good as ever.

Henderson has won six of his last seven fights, including knockouts at middleweight, light heavyweight and heavyweight. That's pretty impressive.

Henderson is now scheduled for a No. 1 contender fight with Lyoto Machida at UFC 157.

No. 11: Johny Hendricks

Johny Hendricks should have GSP scared. Hendricks has now won three straight fights against top-five welterweights.

He knocked out both Jon Fitch and Martin Kampmann, and he won a decision over Josh Koscheck.

He has some of the best wrestling in the welterweight division and arguably the most power. All welterweights should be afraid.

Hendricks will face Jake Ellenberger at UFC 158.

No. 10: Renan Barao

Barao won the interim bantamweight title at UFC 149 with his five-round decision over Urijah Faber.

Originally, Barao had planned to sit on the belt and wait for Dominick Cruz, but Dana White has recently said he will look to have Barao defend the title, which he will do at UFC on Fuel TV 7 against Michael McDonald.

No. 9: Demetrious Johnson

Demetrious Johnson is a one-time bantamweight title challenger and first-ever UFC flyweight champion.

After earning a unanimous decision over Ian McCall, Johnson put himself in the finals of the tournament to crown the UFC's first-ever flyweight champion. He then earned a split decision over Joseph Benavidez and earned the inaugural UFC flyweight title.

He will face John Dodson at UFC on Fox 6 in January.

No. 8: Frankie Edgar

As a former lightweight champion and a man fighting at least one weight class higher than he possibly could, Frankie Edgar belongs this high on the pound-for-pound list.

After suffering a second loss to Benson Henderson at UFC 150, Edgar's shots at regaining the title any time soon are slim, but he did answer the questions about fighting at lightweight.

He was briefly scheduled to face Jose Aldo for the featherweight title, but an injury to Aldo forced the cancellation of the fight. It was rescheduled for UFC 156.

No. 7: Dominick Cruz

"The Dominator" is yet another fighter who was forced out of a fight due to injury.

Dominick Cruz was set to face Urijah Faber for a third time in the co-main event of UFC 148, but a torn ACL forced him from the fight.

Unfortunately, a second ACL surgery has forced Cruz out for even longer, and it is unknown when he will be back.

No. 6: Cain Velasquez

Cain Velasquez can now call himself the two-time heavyweight champion of the world. On Saturday night, he won the title back from the man who took it from him.

Velasquez earned a unanimous decision over Junior dos Santos, in a fight that wasn't even that competitive, as shown by the scores of 50-45, 50-44 and 50-43.

No. 5: Benson Henderson

Benson Henderson got his first definitive victory as the UFC lightweight champion. His two fights with Frankie Edgar were incredibly close decisions that he won, but some fans still didn't see him as champ.

With a unanimous decision over Diaz, Henderson proved that he is, without a doubt, the No. 1 lightweight in the world.

No. 4: Jose Aldo

Jose Aldo remains in the No. 4 spot in the pound-for-pound rankings.

Aldo has decimated his competition at 145 pounds and was set to face Erik Koch at UFC 149, but an injury forced him from the card.

He was once again set to face Koch at UFC 153, then Frankie Edgar, then he was pulled from the card altogether when he got injured. They will now face off at UFC 156.

No. 3: Georges St-Pierre

Georges St-Pierre made his return to the cage for the first time in more than a year at UFC 154, and he had the toughest fight of his career.

For 25 minutes, he and Carlos Condit battled back and forth, and GSP was hurt badly in the third round with a head kick.

St-Pierre earned the unanimous decision win in the end, but it wasn't enough to jump back into the No. 2 pound-for-pound spot on this list.

No. 2: Jon Jones

Following another title defense at UFC 152, Jon Jones just continues to prove that he is one of the best fighters on the planet.

Jones defeated Vitor Belfort by fourth-round submission, and while Belfort lasted longer than most expected, he fell just as the other four former champs had.

Jones is currently coaching against Chael Sonnen on The Ultimate Fighter and will face off against Sonnen in April.

No. 1: Anderson Silva

Anderson Silva moved up to light heavyweight for the third time in his UFC career at UFC 153 and faced off against Stephan Bonnar, a man who had never been legitimately finished in his career.

For nearly four minutes, Silva toyed with Bonnar, putting his back against the cage and just daring Bonnar to strike him. Then, he finished Bonnar with a knee to the solar plexus.

He's the greatest of all time and definitely the greatest pound-for-pound fighter.
