I read something interesting about Brendan Ingle's fighters:
Dancing turned into fighting and pretty soon Ingle, a free spirit, a maverick, the great improviser, was combining the two to concoct a boxing style all of his own, a style imprinted on each of the men he trained, from [Naseem] Hamed and [Herol] Graham to [Johnny] Nelson and [Ryan] Rhodes. Even his lumbering heavyweights boxed the same way. They were all light on their toes, in and out, masters of range and timing, each of them utterly comfortable with their hands down by their sides. They were ostensibly matadors with gloves. Hit and don’t get hit was their mantra...
"It’s all about time and patience,” he said. “I’m in charge. If they look good, I look good. It’s simple logic. If they make money, I make money. Who wants to finish up with a flat nose and cauliflower ears? People don’t realize that a few years ago I started the Sheffield, Rotherham and District Ex-Boxers Association. I came across so many people with flat noses, cauliflower ears and a croak in a voice from being punched in the throat. I wanted to do something to help them.”
Perhaps the greatest testament to the Ingle way – to be elusive, to be defensive-minded – are the coherent voices and clean faces of his retired former pupils.
For example, Hamed, though now as wide as he is tall, is just as brash and fast-talking as ever while the likes of Rhodes, Graham and Nelson have all appeared on television as pundits. What’s more, Nelson now enjoys a role as a boxing presenter on Sky Sports.

It is beyond doubt that Hamed, Nelson, Graham, and Rhodes have come out of their careers in apparent good health and still mentally sharp. It is at least plausible to suggest that Ingle's style - i.e., hit and don't get hit, using reflex and head, body, and leg movement to avoid punches rather than trying to absorb or block them with gloves - might have something to do with this.
