If there was an MMA thesaurus, the antonym for Jon Jones would surely be Georges St. Pierre. GSP is a champion Jones probably aspired to emulate in terms of sheer professionalism.

GSP is widely considered to be the greatest mixed martial artist of all time and very few would argue against the claim. What about Anderson Silva? Well, the Spider's career has a few grey areas whereas GSP's is almost perfect.

He has it all - bouncing back after losses, titles in different weight classes, black belts in four different martial art disciplines and one of the most impressive title reigns in MMA history.

GSP's unlikely knockout loss to Matt Serra at UFC 69 briefly threatened to derail the Canadian's career path. Rush gained retribution against Serra and embarked on a reign that may have seemed boring to a few but in all honesty, was a perfect example of a master strategist getting the job done every single time.

Pure athletes like GSP are hard to come by.
