It would be easy for a fighter like kovalev to be lazy and not improve as his power is a leveler. John david jacks drills he gets kovalev doing are excellent. You can see the imorovement in kovalev when he didnt have john as his trainer.
Hes more patient, his jab is much better. His stance and balance is much better, and most importantly his defence and footwork are far superior under john david jackson.
He is the best trainer in the world imo.
