You're talking about a man who isn't like the normal person. For example, why do millions of boxers try to get the guard to become a second-nature when Ali kept his hands at his hips? Why doesn't all boxers adopt using the Philly-shell/hitman if Thomas Hearns was so successful with it? Why doesn't all boxers just blindly bullrush like Mike Tyson?
A little explanation. Those I've mentioned had something special, which can't really be copied imo. For example some people are just born heavy-handed like Gary Goodridge, Mike Tyson and there's nothing you can do about it.
Some people make certain technique work which honestly, I don't know how to explain why it does, it just does. You can watch all the dvd you want and say "well he does it this way, therefore it must be correct". Nothing I can say except, try it but don't blame me later for not telling you it doesn't work.
Methinks, instead of instructional dvd, get some proper training with a qualified COACH, not pro. I know pros who can't teach a damn, and coaches who can't fight worth a dime but can make people really good.
