Look at Adonis' knuckle-draggin' arm havin' ass. His wingspan is actually more than his height, which qualifies him as a genetic freak in that department, so obviously he's gonna be a good deadlifter. Longer arms relative to your height mean superiority in the deadlift. And when you're pulling 600+ from the floor, no matter what genetically-determined leverage factors you have on your side to enable that, that kind of strength is gonna have significant carry-over into your other basic lifts.
