GSP is never going to be known as the "greatest of all time" He won't Even be top 2. He will be the greatest WW ever, but the dude is a beast and a coward at the same time. He doesn't take risks, never has. Everything he has ever done has been calculated. Even most of his fights aren't note worthy. I mean how many spectacular finishes does GSP have compared to guys like Anderson Silva, Fedor, Jon Jones... This stuff matters when your talking about GOAT.
To most people Silva will always people the greatest ever. The guy has fought in multiple weight classes. He takes huge risks in his fights and he's exciting. Jon Jones could possibly eclipse Silva because he is the same way. He takes risks in his fights, finishes people and wants to move up in weight and challenge himself.
I'm sorry, GSP is the man at 170lbs but he is afraid to take risks, and that makes him a coward.
I would submit that there are lots of folks who have GSP top 2 right now, based on how dominant he has been, the quality of guys he consistently fights, his win/loss ratio, etc.
He doesn't take risks, never has
is simply inaccurate.
