Crawford was 152 lbs against Gamboa. So if the fight were held under modern weigh-in rules, Bud would be 152 lbs, and Steven would be 142-ish at best
Crawford might win on size, but even with pounds on DeJesus this wouldn't be an easy fight. DeJesus had legitimate skills, which is more than can be said for most of Crawford's no-hope opponents.
weight don't tell the whole story. Dejesus was a midget, he'd give a ton of height and reach to Crawford
