Fighting doesn't work like that, unfortunately, otherwise Id be rich AF, especially a fighter coming off a two year lay off and having boxed the majority of that time. Conor has the skills to beat him, he just needs to be on point. People said the same exact thing after the Nate fight, but boy were we wrong. The fight was actually much closer than Silva Sonnen for when it lasted, but a brilliant fighter like Andy made adjustments and finished Chael in short order - there are blue prints for the striker to adapt to the wrestler.
Conor can make massive adaptations and has a great fighting brain that can make adaptations. He is also in uncharted territory having made 100 million boxing and in to all sorts of businesses like cutting fashion deals, running his media company and his new whiskey endeavor, so refocusing could do wonders.
I take Kav on his word and believe that Conor was not 100% and defied his advice to take a tune up fight before Khabib. There have been plenty of fights were lopsided and then the rematch went totally different, and lets not pretend like fight was like Barboza, or even RDA, where they mounted no successful offense and did not win a round. For sure tho, Khabib is an enigma, wrapped in a riddle, and it still has o be cracked. If Conor would get it done, I would say avoid TD at all cost and use the exact opposite game plan as before, which was to pressure Khabib like he did Mendes and be fine with giving up the TD; use the jab for distance, use better angles, look to counter and go back to a bare bone boxing game like he did vs Eddie. Khabib makes mistakes, but most people are too petrified of being taken down that their offense goes to crap..
