Levrone didn't get "owned", he doesn't train for strength. If he got owned it was on stage, not in the gym. Sure, the kid is stronger than him on deads, dB curls etc., but Levrone was training for size. His 100 lbs DB curls were just a throw-in-do it for the camera.
Besides, in terms of genetics someone like Levrone is top of the pop in relations to responding to gear. The kid is obviously top of the pop in the natural strength department.
