Georges St. Pierre is widely regarded as one of the best pound-for-pound fighters in the world. His skill set is off the charts and he has been the UFC Welterweight champion for three years.
He hasn't lost a fight since April 2007, going 7-0 in that stretch. He will defend the welterweight title against Josh Koscheck at UFC 124 in his native Canada.
As is the case with any great fighter, it's always fun to speculate about fights that would be fun to see for one reason or another.
Here are the top 15 fights that we would like to see GSP have. Not all of these are realistic because there are weight class differences and fighters are in other organizations. These are just some dream scenarios that would bring tons of business to MMA.
The first fight on the list appears to be the closest one to actually happening. Dana White has said that Jake Shields will get the next shot at the welterweight championship, assuming that GSP wins or Koscheck wins in dominating fashion.
Shields is a great ground fighter, maybe not the most exciting fighter, but he knows how to work the ground and he wins.
It would be interesting to watch how the styles of GSP and Shields would play out inside the octagon. GSP would be a heavy favorite, but Shields could pull an upset.
Fitch wants to get a shot at GSP and the welterweight title as we speak.
However, assuming that GSP wins at UFC 124, the next shot appears to be going to Jake Shields and leaves Jon Fitch standing in the cold.
He won't be alone for too long, though, as he gets a fight with BJ Penn in February.
A bit of Machida's flare has been taken off with two consecutive losses, however, the contrast in styles could make for a great dynamic in the octagon.
Machida's defensive-aggressive style against GSP's lightning-quick strike ability could make for a great back-and-forth fight.
Gilbert Melendez is becoming one of my personal favorite fighters.
His performances are consistently great and he is getting bigger victories each time out. His domination of Shinya Aoki was a striking clinic, and a fight with GSP would be one for the ages.
Rua's biggest problem has been staying healthy.
If he could stay healthy for a prolonged period of time, he could climb back up the pound-for-pound rankings once again (not that he is very far down the list right now anyway).
Besides that, he is the best fighter in the best division in UFC, so that has to say something.
Alistair Overeem is more focused on his kickboxing in K-1 right now than he appears to be on MMA.
But the Strikeforce Heavyweight champion taking on GSP could make for a great fight with GSP's BJJ style and Overeem's terrific submission ability.
Fabricio Werdum was able to take one of the most unbeatable fighters in MMA history, Fedor Emelianenko and got him to submit in the first round. Why couldn't he do it to GSP?
He can build a reputation as "The Legend Killer" a la Randy Orton in WWE....except this would be real.
One of the best talkers in UFC going up against one of the best pure babyfaces, Evans vs. GSP would be money because of the talking that Evans would do leading up to it, and then the action between the two men inside the Octagon.
The WEC Bantamweight champion can be the inaugural UFC Bantamweight champion with a win over Scott Jorgensen in the final WEC event.
Cruz is an all-or-nothing kind of fighter from the standpoint of he will knock you out or the fight will go the distance, nothing in between.
It's such a shame that Aldo got hurt in training for his Jan. 1 fight against Josh Grispi and the fight had to be postponed.
He is a very unique and dynamic fighter, much the same way that GSP is, it would make for quite the interesting fight between two great tacticians.
Fedor has been, arguably, the best heavyweight fighter in MMA for most of the last decade.
Even after his loss to Fabricio Werdum earlier this year, he is still one of the best fighters in the world and a fight with GSP would be a dream come true for a lot of MMA fans.
One of the best wrestlers in the world, Frankie Edgar, bringing his style and quickness into the Octagon against GSP and his all-around ability would make for an interesting and fun dynamic.
The best heavyweight in the world against the best welterweight in the world.
Cain Velasquez became an instant sensation with his performance against Brock Lesnar at UFC 121 and a fight with GSP would be absolute money.
One of the most rumored and anticipated fights that has yet to come to fruition.
It seemed to be on the agenda but then Dana White put the hammer down when Silva put on a God-awful performance against Demian Maia at UFC 112.
The two best pound-for-pound fighters in the world today, the order changes depending on who you ask, could make for one of the most memorable fights in MMA history.
What would undoubtedly be the biggest money fight in UFC history, Brock Lesnar vs. GSP is the biggest dream fight in UFC.
It would feature the two biggest draws in UFC today going head-to-head in a fight. The anticipation would be off the charts and come fight night, the buy rate would be the biggest in UFC history.
