Those LB' aren't leaping with 30-40 inch verticals for the most part. Not sure how they measure it, but I don't see it. I used to squat a few 4-500lbs back when I played and at 6'2" never got near that vertical. Could dunk a nerf ball maybe. I find it hard to believe that all these lb's are getting that kind of vertical. I know that they are high level D1 athletes, but lots of these guys as Marillac pointed out, aren't built that way and built for a different kind of speed and power.
