I would actually say Chad is much better at getting takedowns than Khabib, especially at the type of distance Conor is known to keep, but Khabib is far better at controlling and damaging someone once he has them down, Conor's biggest worry against Khabib will be getting trapped against the fence, coz from that position Khabib has looked unstoppable and will probably be able to get Conor down relatively easily.
I think it's underestimated just how good Conor is at punishing fighters who get into the kind of range Khabib will need to be in to implement his gameplan.
Just look at how well Eddie was able to press Pettis and Melendez against the cage in their fights, and compare it to how badly he was punished every time he got close to grappling range against Conor.....
If Conor can land on Khabib early, which he has been able to do against everyone he's fought, Khabib will become hesitant, it's human nature, and the more hesitant he becomes the more openings Conor will find.
The fight has to happen, there's nothing out their as intriguing.
Oh and Chad did not suddenly gas out, Conor gassed him out...
