So he mixes this up, either he throws it and clips you. Or if you are expecting the punch, he takes you down. To combat this, you'd have to train yourself to prepare the dip for takedown or wild throw. I see conor unprepared for this, because it was a well known fact before the fight that Khabib does this all the time. Even watching training clips of Khabib before the fight, you can see him training this shot. Then altered it, its only milliseconds where he dips down, then fires the right.
