His biggest issue has shown to be stamina and I think that would be a better aspect to work on.
He's dominant now. His loss to the P4P king doesn't affect the way I view him as Floyd Mayweather Jr beats everyone. Improved footwork would not have helped him to beat Mayweather and with his current footwork he's beaten everyone else
Improvement in footwork couldn't hurt, but he needs to work on stamina. In order for his power and speed to be fully effective, hr needs to be able to throw continuois combinations in quick succession.
tt would do him good especially if he could also develop better hand to feet coordination to go along with the improvement in his footwork.
It's safer to say my boy needs to work on his stamina more.
