The best up and coming "Jr" hands down is the kid Darnell Jiles Jr, seen him a few times on Espn friday night boxing and oh my lord the kid is gonna be very special, i'd back him to beat anyone of that list and he's only 18, those who have seen him may be inclined to suggest he's a little "flashy" but imo he's got everything in his game,

Confidence

Speed

Technical ability

Power

movement

Decent defence

And he can punch from some mad angles man , i think he's a cert to be a champion with-in 3 years,

peace
