That's has been my problem all my jumping life: I can't amortizate in the quads. I might have faulty mechanics and overload the quads too much in the plant, but they ARE the limiting factor because they limit my ability to use momentum. You don't really need to be able to put out THAT much force voluntarily if you can use the accumulated kinetic force during the run-up in your plant.

But in order to do that you need to be able to stop the forward momentum and make it convert into upward thrust. To do that you need the best brakes in the world. The brakes are the quads because they prevent the knee collapse. So basically you need great quad eccentric strength to decelerate.

That's why I'm trying to forcefully decelerate after sprints... to learn to manage the high quad eccentric load... kind of like in a depth jump. I remember Adam Linkenauger recommending against a quick deceleration after a sprint as it might be injurious... but I kind of use that as an exercise in itself.

Is it just me or all these guys put in A LOT of quad in their jumps? Looks like a lot of knee stress as well.

Well the human is the worst kind of animal ever.

I will try that but from what I'm aware of, the ITB can't really be stretched... it's just a myth. It doesn't respond to stretching.

This goes beyond me.

My measurements indicate a 49 inch vert... although you can't see his legs touching the ground on the landing so it's just speculation, but it has to be pretty close. Doesn't look like an all-effort max jump either.

Bone density improving in two weeks? I don't think so.

But really, the advantage of plyos vs. strength training is that only the plyos overload/or load at whatever intensity - the lower legs. In the squats and deadlifts the lower leg isn't nearly as active as in a plyometric effort, even at medium intensity.
