As slick as he is, most guys who make successful (and dominant) moves through multiple weight classes start off at their lower weights with world destroying power. Lomachenko is as slick as anyone I've ever seen and could probably just purely box his way to a lot of 12 round decisions on the way to titles at 135 and maybe 140...but the more you move up, without power, the more that turns into walking a tight rope. Sooner or later, someone who has to cut 10-15 pounds to get to the weight you walk around at, is going to catch you with something heavy.
He could clean out 135 though, Garcia getting lucky with a clean shot is the only speed bump I see in the way. 140 though...Terrence Crawford is a bad man, and a fair bit bigger. Would be a legitimate superfight though.
