Have only seen so much of both (like 5 fights) so take that with a pinch of salt. Yuri, to me, looks all wrong for Pong. Pong liked to establish lead-foot dominance and kinda probed with his jab, a bit. Yuri wouldn't let him do that as he had a better jab, and would take full advantage of the extended arm to snipe Pong's right ribs. He also has the better, quicker feet and would be better at establishing his lead-foot. Pong also liked to dip at the waist to his right/Yuri's left. Meaning he's in perfect line for double uppercuts, which Yuri would clock onto and use. As an aggressive, in-your-face southpaw, Pong was in line for a solid 1-2; Yuri's was among the best in flyweight history. Pong's chin can't take that heat after 7/8 rounds IMO. The punch which took Kittakesm out would do the exact same to Pong. Yuri's defence was good, but his reflexes weren't Lomachenko-escque, and so Pong would land. It'd be an awesome fight where the versatile boxer-puncher picks apart the in-and-out southpaw with his bag of tricks and a great 1-2. Arbachakov late TKO.
