I think Zurdo hits harder than LSC, he seems to punch with more conviction and in general it sounds more thudding, not to mention he's got a higher KO percentage.
Zurdo got marked up pretty good against Vlasov, who was hitting him at will at times....GGGs skills are on another level, hed massacre Zurdo
He's all wrong for Golovkin. His shots would leave him extremely vulnerable. Golovkin would have a field day. I don't see him making MW anyway.
