what drugs are u guys on?
the legs bend and straighten. you increase your ability to do that with more weight and your leg press/ squat goes up.
besides, who cares?... put the same amount of effort into LP as you do squats and you'll grow..in fact your legs will respond even better cos you can concentrate your energy into only the quads/hams and not share it with lower back and trying to keep coordinated.
the thing most people do wrong with LP is they go too light and not deep enough...
lotsa people go super heavy and move it 1/4 or 1/2 range...waste if time.
then we have those who go super deep and too light and end up doing 20+ reps.
Go beyond parallel, stack on as much weight as you can do for 8-12 reps. not rocket science.
most people underestimate how much they can do for this, and instead of hitting failure right at 12 reps, they just stop..if u are doing that, you havent got enough weight on the machine.
an experienced gym rat should be using 600+ lbs depending on height/weight..
ive seen swimmers (actual competitive, national level) rep 660lbs for a couple at under 200lbs. not WR stuff, but these are guys who dont train for strength or size.
Squat is very much about the mechanics that you have genetically, LP removes alot of those limitations.
