question-
how much is it there not being enough trainers who know what to teach and how to teach it; an how much of it is the fault of the promoters, who want to get a kid out there and maximize their earnings. Or the fault of a fighter who either a)is so limited he can't develop the skills fast enough to be competitve OR worse yet said boxer has already reached a certain level of success and isn't willing to take direction, instead seeking to get rid of said trainer.
part of doing something is having faith in it and in alot of cases if a boxer isn't buying what your selling, that boxer won't execute as well, cus he has no faith and no will to do so. Its the same w/a system in football or baseball or basketball etc; people will stick w/what they feel comfortable w/moreso than what is new or unfamiliart, i always thought part of the reason hopkins developed like he did is due to his limited b/g and the fact he lost his first fight and because he never had great phys ability, he had no choice but to get better an learn every trick. He wasn't good enough to fight any other way, unlike a de la hoya or roy jones jr or vic darchivyan or malignaggi and so on..etc All of whom had alot of success and had exceptional ability.
