Two reasons.
1) McGregor tore his ACL a couple weeks before the fight. For all you tubby lards, this is as serious knee injury as it gets, you lose all stability on that knee. Generally takes 12 months of proper rehab and training and it never really is the same. This is a significant factor in why mendes could take conor down.
2) This one is very important. McGregors game has changed quite a bit since that fight, he is nowhere near the same fighter and has completely refined his game (cheers diaz).
Output has decreased quite a bit, no more balls to the wall with a variety of strikes, he picks shots and uses the same ones over and over and throws a spin kick sparingly. Conors abiltiy to adapt to his strengths has been remarkable and his TDD has improved by a mile as proven in the alvarez fight (Inb4 retard haters bring up Diaz fight while not realising conors style has also changed afterthe diaz fights, now adding COMBOS to his crisp punches as well).
Conor is going to crack khabib with his superior striking and its gonna get nasty early. Khabib may survive but given how rudimentary his standup is khabib will likely panic and shoot from the hip.
TLDR
Healthy, refined game conor is nowhere near the same fighter as he was against Mendes and drawing conclusions from that fight is STUPID
Your "hero" has not fought for the past 2 years.
To claim he is "refined" or "improved" is asinine since you have absolutely no idea what his 2 years of inactivity might have done to his game.
but beyond that, Conor McSuckers are far too desperate to disclaim that fight ever happened.
They give all kinds of excuses (like his "injury") while completely discounting that Mendes had absolutely no camp.
Highly hypocrite of their part IMO.
But the main point is that Conor's game is standing up. Khabib's game is on the ground.
This fight is a clash of styles and NOTHING will change that.
If you want to claim Mendes fight never happened, that's fine. But that does not mean Khabib won't be able to close the distance and take Conor down.
I don't know who will win. But whoever wins, will make it look easy.
Whether is Conor KO'ing Khabib when he shoots, or Khabib overwhelming COnor for a TKO or decision victory... it will be a domination.
But to claim either can't happen is just pathetic wishes from a desperately blind nuthugger.
...well.... maybe not so blind, since Conor fanboys keep trying to convince the word by making threads after threads about the same thing...
