Bas Rutten knew all along how to defeat Conor Mcgregor:
“So if I would face Conor McGregor, I would tell my students to start switching stance and low kicks – because for him (Conor McGregor), it’s going to be impossible to block this (outside) low kick. And especially if he’s standing like this, you’re not going to be fast enough. Low kicks attack on that front leg in the southpaw position that would be my advice if I had a student who would fight Conor McGregor. Because then you have a target; otherwise you don’t have a target, you might kick a knee (with the inside low kick).”
“If he (Conor McGregor) checks them (the outside low kick), they’re going to kick the calf and the calf is going to be relaxed when you lift it. And a relaxed muscle, same as with the body shot, if the muscle is relaxed and then you kick it, then you go down.” (*H/T Sportskeeda for the transcription)
