Billy Graham was a boxer who by his own admission trains pressure fighters because as a boxer he knows the trouble pressure fighters can give you, and how (or words to that effect, bbn interview a while back)
or, not every fighter Richie Woodhall trains looks like a European amateur style fighter behind a jab and double guard
similarly i saw an interview with farnell (again bbn) where he said it absolutely wasn't his intention to turn out a string of clones and that he'd be a lot more, umm varied in his approach to training than he was in his own fighting. I seem to recall him saying something along the lines of 'I never got much attention from my trainers so i will make sure all my fighters get 100% attention from me' plus as alredy said few will be able to imbue a fighter with dedication for the game and fitness, as well as Arnie
