Hard fight really. Hill is in his own division and has incredible foot speed to go along with an accurate jab. And he has a great chin. JC is a southpaw which will trouble Hill and throws many shots and is pretty quick. However Hill won't stand in front of JC.
Calzaghe convincing points decision, he takes away the jab of Hill and after that, Hill can’t compete with him. They’re a different class of fighter.
iirc, it was mentioned during the DelValle fight that Hill had little (or no?) pro experience vs. a southpaw, & it showed during that fight. though tbf, Hill did eek out a win over a sleepwalking Maske in his next fight.
He figured out Masks who was an extremely difficult southpaw. I think Hills movement would give JC fits.
