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.
