GSP attended UFC 196, which started a strong rumor that if Conor won that fight, GSP and Conor would fight at UFC 200.
Diaz gave his thoughts on that.
GSP is rumored to be returning to the UFC this year.
GSP last fought in November 2013 when he won a close and controversial split decision over Johny Hendricks.
Nate Diaz will likely rematch Conor McGregor at UFC 200 on July 9th.
Kenny Florian says GSP is returning this year for sure, and may fight in the first UFC event in New York.
Firas Zahabi also guesses that he returns this year.
And Renzo Gracie says the same thing.
