He was a full-sized LW who peaked very high and fell very abruptly, for obvious reasons. He's appreciably better and a bigger hitter than any LW Lomachenko fought. It was silly of me to bring up who would be favoured in terms of betting odds between men who existed on the earth at the same time for a year or maybe two, but De Jesus would be a much more interesting proposition than anyone Lomachenko has fought to date, and it's completely reasonable to think he could beat a guy like Lomachenko. Lomachenko is a rather small LW, and he's not the kind of guy with the abilities to overcome considerable size and strength disadvantages against guys who are properly elite, at least, that's my opinion.
At his best weightclass (in my mind likely FW even if he'd be a bit tested to make it at his age now), he'd give most guys, even ATGs, all kinds of fits, but LW is a different kind of beast.
