If Chris Weidman beats Anderson Silva, GSP could be the greatest ever

Anderson Silva was widely considered the greatest of all time in MMA. But if loses to Chris Weidman again, possibly Georges St-Pierre could creep up behind him and overtake Silva as the GOAT. Others may point to Fedor Emelianenko, but GSP's 25-2 record over 11 years, and avenging his two losses, makes him statistically the greatest ever. Silva was more creative and devastating, and an incredible artist in addition to being an athlete. But based on pure numbers, Georges St-Pierre is the greatest ever.
