Thanks for the infos. I train a little boxing, so i got a notion for the basics, but been able to readjust from a slip to a duck seems to me high level stuff. I understand the movement, but been able to do it in the time lap you need to see the punch, start the motion, realize it's a hook not a straight, and be able to readjust...
One other thing i find dangerous is the lead hand been low, while slipping to the left. Obviously he knows what he's doing, but to me it's seems unsafe. Again, if he goes into a hook, there is nothing there to protect him.
