I've watched a lot of real street fights on the internet. A common technique is where the attacker grabs the shirt of the victim with his left hand and throws non stop punches with his right hand (reminds me of Keith Hackney vs Royce Gracie). The left hand grab is up by the lapel / center chest area and the right hand punches are generally straight and fast (maybe 2 or 3 punches per second).
How would you defend against this?
