In the vast majority of boxing gyms that American fighters start training, Olympic boxing is a bit looked down on. I've been told by trainers "I teach real boxing, pro-style." I think in most gyms, there is an emphasis on pro-style fighting, yeah, when they climb the amateur ranks and get the international level, they are at a disadvantage to teams who train their fighters from the start develop styles that result in better scoring with international rules.

Fightfan brings up a good point that the least experienced guy probably listens better. A lot of these guys have a chance to be much better pros than amateurs and a lot of the metal winners won't ever do anything at the pro level.
