31. Robert McCracken
McCracken is one of the UK’s most respected boxing coaches. After leading Team GB’s boxing team to glory in London in 2012, he became Anthony Joshua’s head trainer. Joshua became a feared opponent but McCracken failed him on a couple of occasions (via DAZN).

The trainer’s bizarre gameplans against Andy Ruiz and Oleksandr Usyk cost him dearly. Joshua failed to make use of his physical advantages in either of those fights. It appears as though McCracken is more compatible with amateur athletes than top-level pros. It will remain to be seen if McCracken remains training truly elite professional boxers in the fore
