Boxing is like any trade you need to learn it thoroughly yes having gifts like speed or power may get you far or maybe win you titles but you will get found out sooner or later. Eubank Jnr is anther example of this I believe even if he was thought well and went through the amateur system he still wouldn't be a world beater but he would have been far better then he is now a billy goat with no brain cells in the boxing ring..... For example something simple about setting up your shots at the highest level it takes time and experience to master this art its not just about ragging in and trying and hoping to hit a target. You need to have good foot placement start of with the jab work your way through see where you can come in before actually trying to etc.... You need to learn your trade well I like how the eastern Europeans go about it they spend 10 years or even more learning different styles because in the ams you come against every style possible then only then they venture in to the pro game having the experience of the different styles this helps them tremendously
