I don't think u get in cage like that, almost every boxer who fights in cage know/can do all the things u said else he wouldn't be in the cage isn't it? I mean u can't start doing competitions 'like that'. For me the best part is the training, when I train my ass off till I just can't move anymore I'm much more satisfied than beating some amateur on a ring. If u train harder than the fight itself u will win, why do u think tyson was so strong? He had no f***ing life, he was a 'nerd', training everyday of the week and ofcourse he had a natural talent for boxing but that talent wouldn't have developped so far if he didn't train so much
