Here's video of Roy Jones Jr.'s kid, Roy III, using his dad-given athletic ability ... but NOT in a boxing ring ... 'cause it turns out the kid is an absolute terror on the hoops court.
16-year-old Roy III is a junior at Pine Forest and by the looks of his highlight video he's doing the same thing to his HS competition that his pops did to his foes in the ring ... making them look silly.
It's not just flash though ... kid's got the numbers to back it up .
