It is not like McCracken doesn't know anything about helping fighters to let their hands go and go to war. Froch even with his hands down style was hardly a gunshy defensive master. Usyk was the first southpaw Joshua had fought since destroying a very limited Charles Martin and it proved to be a big factor. Usyks performance on the night and Joshua's decision to come in smaller than usual did more in nullifying AJ's reach and power punching advantage than any tactical choices by McCracken.

Usyk upped his game considerably on the night with a superb display of concentration. If Joshua wants to be more unpredictable then coming in much bigger and changing his coach might help, but if he had let his hands go like he has in previous fights, McCracken would not be made the scapegoat he seems to be now.

Nobody but AJ can change his pyschological approach and changing his coach might be more about AJ signalling that than any great tactical overhaul.
