I definitely see smaller guys pulling impressive numbers sumo style in the gym, but they can't bench or squat for shit. Unfortunately for me, the deadlift is my weakest movement, with my best being 405 at a bodyweight of 193, conventional style, when I could bench 355 and squat 455 at that same weight, but my hamstrings suck, though.
Good benchers are built in a way that it works against them in the pull and vice versa
