I think garcia is a great coach and seems also like a great guy. Also his measured aggression could be good long term for aj. but this is a real short space of time to build a relationship together and for him to make significant changes to aj’s game both physically technically and mentally.
The right trainer for a fight against usyk where joshua has to press the issue. Garcia is a master at that. But long term not so much
This will lead to another KO loss for AJ. He's vulnerable to counters. It's why he stopped fighting like that in the first place.
What choice does AJ have - against a master like Usyk. Better to take your chances and go all in. Attack is the best form of defence.
