This is the problem with wing chun today, Although I can appreciate what Dominick Izzo is trying to do, he is using the same chasing straight line footwork like most wing chun people today in a boxer's range, very few seem to use the angular approach in your face approach that wing chun was designed to use. From my experience a boxer will eat you alive if you fight this way. http://www.youtube.com/watch?v=IXzzg2ZnTMc
