Who the fuck knows, GSP is obviously a naturally gifted athlete but I've seen more than a few things that make me lean towards BJ's opinion. That being said, it truly is unfair to shit on someone without hard proof and it was an era in which many, if not most, were on something so I hold the view of innocent until proven guilty. With that said, I consider him the clear cut WW GOAT and possibly P4P, as well. Very few fighters can claim to have wiped out nearly every ranked opponent in their weight class over years, left no defeats unavenged, and won a second title a weight up post-prime.
