thank you for asking my opinion.
I did not see the fight and now you have my interest piqued greatly as to the corner work. It is a very important factor and always has been.
If I could only see a copy of that fight I would be happy to respond in full to you.
When Jack "Doc" Kearns used to be in the corner of Dempsey, he would say to him, "Jack, pull up your socks and knock him out." Dempsey would usually oblige.
When you have a Mickey Walker or an Archie Moore doing the job on someone as old Doc did in later years advice is not too necessary.
99% of the rest of the time it is invaluable. Motivation advice from someone a fighter loves and trusts has it's value, but nothing replaces working on different scenarios geared to respond to a particular opponent one has worked on with a trusted trainer. You have to have a game plan in the ring.
You have to work on specific things to adapt and be prepared to execute them with great conditioning and practice.
That is what the gym work (In private) is for. It is all business to me and I know how to prepare for every scenario with a willing charge.
As to Gatti and Mayweather, nothing would save Gatti except doing things like Al Bummy Davis did to Bob Montgomery. When you have someone with greater skill, speed, conditioning, and all you have is a big left hook like Gatti, there are ways, good buddy there are ways to get the job done.
Some corner men are paid big bucks and don't do ANYTHING because boxing is in such a sad state, even the fighters sometimes don't know the difference between bad advice and what is really needed. Just look at the films of the Tyson V Douglas fight in the corner. A dangerous, pathetic joke.
Sometimes a skilled fighter who becomes a trainer just cannot adapt to giving the proper advice that is beyond his scope of thought to defeat an advesary that is destroying his pupil's planned gameplan.
This is my theory, always has been, I know how to hurt a fighter right away, how to teach it, and how to maintain the speed and puching power to hurt everything you can hit. It comes from a mixed boxing and MM Arts background. Problem, to execute it almost no one wants to train themselves into the level of Jack Lalane conditioning to execute it.
E.g. If you hit the heavy bag or spar for 4 rounds, you can do it in a manner that accomplishes nothing to prepare you for an all out war OR you can train in a way that prepares you to put out like a Ferrari burning gas from the fires of Hell.
Then there are drills of speed, drills of punching power, etc.
I am getting old now, but what I could do with some of these guys breaks my heart if I had the chance whether it was the UFC or a major fight.
I just know exactly what you mean, and I think it extremely astute of you to notice these things like the other great boxing fans out there. It never fails to amaze me when I see how much you guys notice. Bravo to you!
