My amateur coach had told me about it and said it was a check hook a few years back and i practiced it a lot but i just saw it as an advanced counter left hook(more complicated since you have to get out of the way at the same time with your back foot). After the fight the technique has gone around the world. Any other examples of good check hooks in recent fights?
I bet not to many, but after that fight everyone was acting like it was part of their vocabulary for the longest time.
