I have never done it but somebody else may have thought that it needed to be done. I can't think of a reason that would make me say that.
Maybe to instill confidence in a fighter who might be doubting themselves or if they have what it takes. I think it could certainly be used in a positive light. Though I agree, not at all times or maybe even most times.
Oddly enough, I don't only talk about Size and Power. in fact, I'll think you'll notice we've never even got into a discussion about, nor am I one to go back and forth on the topic. My point is, and has been, there are obvious reasons why those factors matter. They make a difference in the ring. They can be the difference between winning and losing. So imo it's weird for somebody to then ask... Why does size matter(and in this thread you seem to question why power matters)? Does that make sense?
You talk about it so much you made a completely separate thread for it. I don't think you're informed at all on my position on the matter. I've always said that size matters, the degree to which depends on the fighter. A fighter such as Dempsey was 192 in tip top condition and fought in a style that provided problems for big men. Now a guy like Jersey Joe Walcott or Max Schmeling didn't fight in a style that was particularly difficult for big men so size would play a far more significant role. It's boxing, you have to treat every fighter on an individual basis. Blanket generalizations aren't applicable here. My main point isn't that these factors are irrelevant, it's that posters (particularly modernists) put far too much stock into them.
Watch Arguello vs Costello. AA is past it and Costello is scoring and moving with combos. Watch AA set up the right-hand and knock Costello out with one punch. Technique and power!
Power and technique are means to an end, not the end in itself. Technique, in particular, is intimately tied into what type of boxer you are, what you wish to achieve in the pursuit of victory.
Technique Timing Defense Stamina/endurance Accuracy Chin Speed Power Assuming both guys are in the same weight class, power is the dead last thing a coach should focus on wether teaching the basics to a new student or preparing for a title match. However, acting like it doesnt matter is equally foolish. The last 3 categories are "x factor" intangibles that can change a fight like a Thanos finger snap. Fighter A can be better in literally every other category except one of those 3 and that could end up being the one factor that affects the outcome of the entire fight. Not always, but it happens often enough. But having good technique, stamina, defense, etc will help a great fighter pull through despite the odds. Those primary categories are what separate good from great fighters. Otherwise, only focusing on your x factors will lead to more Amir Khan, Earnie Shavers, Ruslan Provodnikov types.
Agree completely, tell a fighter he is a power puncher he turns into a Razor Ruddock. Whenever a fighter starts asking about power and how to hit harder my answer was always learn how to throw punches and combos the power is their or it isn't. If he doesn't get caught up in it just teach him how to box period the fine tuning for his strengths comes later.
The harder puncher when its a close skilled fight will win most of the time. You are just fooling yourself. Having K.O power is a major plus in a sport you are hitting the other guy in, that's common sense. The training things you stated is true!
