UFC Upsets: Where Would a Rampage Jackson Win over Jon Jones Rank?

At UFC 135 this weekend, Jon Jones will defend his light heavyweight title for the first time against a former title holder in Quinton "Rampage" Jackson. 

The trash talk between the two fighters has been epic, so fans analysts, and even fellow fighters seem to be heavily anticipating this main event bout.  

"Bones" is a massive favorite in this one, with the Vegas odds pitting him as a six to one favorite, a figure rarely seen not only in MMA, but really sports in general. 

That raises the question: where would a Rampage win rank among all time upsets in MMA? 

Let's take a look inside at some of the biggest upsets in MMA history. 

Mirko "Cro Cop" Filipovic vs. Gabriel Gonzaga

After the UFC brought Mirko "Cro Cop" Filipovic over from Pride, his first fight was with Eddie Sanchez at UFC 67.  

Cro Cop won with ease, scoring a first round knockout.  With that result, combined with his reputation coming into the organization, it is no surprise that Filipovic was then granted a title eliminator bout with Gabriel Gonzaga at UFC 70.  

In a shocking turn of events, Gonzaga knocked out Cro Cop with a head kick with seconds left in the first round.  

Cro Cop fans had to be in utter shock and awe, given the Croatian fighter's signature phrase of "Right leg hospital; left leg, cemetery."

Gonzaga went on to face Randy Couture at UFC 75, where "The Natural" picked Gonzaga apart with his signature mix of cage control and freestyle wrestling, before ending it in the third round with ground and pound.   

Matt Serra vs. Georges St-Pierre

The shock heard round the world? For thousands of MMA fans it was. 

On April 7, 2007, Georges "Rush" St-Pierre met Matt "The Terror" Serra in the Octagon.  Serra earned his welterweight title shot by winning season four of "The Ultimate Fighter." 

A massive underdog, the Renzo Gracie black belt got the fight to the ground and the submission specialist actually finished GSP with some vicious ground and pound from the mount position.

The punches to the face actually caused St-Pierre to tap before the ref stopped the fight, crowning a new UFC champ at 170 pounds.

A herniated disk in his lower back kept Serra from fighting for a year, and his first fight back with a rematch with GSP.

GSP convincingly beat Serra in the rematch, finishing with knees to the body in the second round.  

Despite a lackluster fight career afterwards, Serra remains one of only two fighters to defeat St-Pierre; the other being Matt Hughes.  

Randy Couture vs. Chuck Liddell

In a match up between two pioneers of the sport, Randy Couture took on Chuck Liddell at UFC 43.  

The Natural was expected to put up a fight due to tremendous grit, determination, and tactical skills, but most fans and analysts expected Liddell to walk away with the W.  

A large part of this was the fact that this bout would be Couture's debut at light heavyweight. 

Despite being well known as a freestyle wrestler, Couture outstruck Liddell for three rounds on the feet, being finishing with ground and pound from mount.

This gave Couture the interim UFC light heavyweight champion, which many agree is what gave him his "Captain America" nickname: this marked the first time a fighter won a UFC title in two weight classes.

If the term "interim" isn't impressive enough, Couture went on to defeat Tito Ortiz at UFC 44 to win the official UFC light heavyweight belt.  

Tito Ortiz vs Ryan Bader

Coming into this fight on July 2nd of this year, Ortiz had not won a fight since defeating Ken Shamrock on October 10 of 2006.

Since then, "The Huntington Beach Bad Boy" had a record of just 0-4-1. While the fights were against high level competition, no one gave Ortiz a hope and a prayer against the former "The Ultimate Fighter" winner.  

Bader entered the cage that night with a record of 12-1, with a very excusable loss to Jon Jones at UFC 126.  

Unbelievably, Ortiz rocked Bader with a right hand and sunk in an arm-in guillotine as the dazed prospect tried to scramble back to his feet.  

After fighting the submission for a few seconds, Bader gave a feeble tap before the ref stepped in. 

Fans loved seeing Ortiz's infamous "Grave Digger" celebration after the fight, and despite Ortiz's loss to Rashad Evans in his subsequent fight at UFC 133, fans rejoiced seeing Ortiz back in vintage form even it was the very last time.  

Fedor Emelianenko vs. Fabricio Werdum

Fedor Emelianenko took on Fabricio Werdum in the headlining fight at Strikeforce's June 26 card of last year.  

Not suffering a legitimate defeat in over nine years and coming in with a record of 31-1(1), it is no secret that "The Last Emperor" was heavily favored in this fight. 

However, many fans realized that Werdum stood at least half a chance if he got the fight to the ground: "Vai Cavalo (go horse)" is a second degree black belt in Brazilian Jiu Jitsu. 

In 13 wins Werdum had eight wins via submission.  Thousands of fans were stunned when Fedor became the ninth. 

Werdum was knocked down just seconds into the first round, and fans were enticed by the fact that Fedor did not hesitate in following him to the ground.  

This move proved to be a massive mistake, as the Brazilian sunk in a very deep triangle choke, which he transitioned into a triangle armbar. 

Emelianenko fought the hold as long as he could, but eventually he had no choice but to tap. 

Werdum has since lost a rematch with Alistair Overeem, while Fedor has dropped two more fights to Antonio Silva and Dan Henderson respectively.  

Regardless what has happened since then, there is no doubt that Werdum's submission win over Fedor was certainly one for the ages.
