I was watching this video by Firas Zahabi (GSP's head coach) and he was saying that if you get caught with a banned substance, you should be banned from the sport for life, stripped of your titles, excluded from the HOF etc. He said that since Jon Jones has popped several time, he cannot be the GOAT. He then proceeded to state that if anyone he constantly praises (GSP, Khabib, Mighty Mouse etc) popped, he would remove them from the GOAT convo.

This got to me thinking, was GSP really clean? He competed in the pre-USADA era and was going up against roided freaks like Big Rigg Hendricks, Matt Hughes etc. Was GSP such a good fighter that he was able to be 100% natural and still defeat all those legends who were most likely juicing? As we all know, PEDs give a HUGE advantage so if GSP was really clean, his reign is all the more impressive imo.
