That mega fight must happen

The longer it goes, the less hyped I am for it.
If it's going to get done, get it done already..

He'll be 40 years old if the fight happens, it's gotten to the point he's too old now

Its gonna be even more rewarding for GSP if he beats Khabib in his 40ies lol

GSP don't do it. The game is getting to different, Bisping was one thing. Khabib and Usman are animals.

GSP please do it, you wont be able to cuddle yourself into another win

GSP is not delusional. He knows the risk vey well and if he still wants that fight its because he really thik he has all the tools to beat Khabib.. He is aware of the fast evolution of the game as he said that many times.
That being said, the way Khabib fought vs Gaethje, man ! He's a different animal fight after fight. Iron chin and pretty good in the Bjj department as well. Very complete fighter. I want to see him vs someone who excel at transitions and Octagon IQ. GSP is very analytic and cerebral. He will adapt to Khabib but is Khabib can adapt to GSP ? We'll find out because this fight will happen

gsp is broke at this point, ran from usada before ufc actually paid their fighters

If GSP was still in his physical prime I would probably give him the slight edge. But he’s old, and if he loses any quickness I think it will cost him dearly. I know he wouldn’t even be talking about the fight if he didn’t believe in himself, but I just don’t know at this point.
