I'd love to see him unify lightweight then challenge the WBSS winner. There's a number of good potential fights for Loma on the horizon. Between the lightweight unifications, the WBSS winner, Berchelt,Tank, Haney, Teo, heck even Mikey...no shortage of names worth fighting even if a name or two just listed doesn't want the job
Lomachenko wouldn't dare go near a badly faded 40 year old Pac at 140 or any weight. He's not fighting any 140 pounders.
