It's interesting that you haven't included the 1-leg RDL as a strength exercise. I feel like my glutes work very well using it, and it's one of my favorite exercises.

Well the first leg is definitely the loaded leg ... the amount of load differentiates the good, reactive kind of people vs. the non-reactive jumpers.

It's interesting how his left palm is on the right side of his body at 00:09 when he jumps.

Probably because you're even less reactive/you're not yet aware of how to use a shorter last step/you learned to reach out to the rim from basketball.

This guy looks like DeFranco in a Rafer Alston+Dave Chappelle body. But he's pretty solid in what he talks about (hence the DeFranco allusion).

As for the depth jumps, I think the only positive part on a depth jump onto a box vs a depth jump to touch something high is the diminished GCT for the on the box depth jump. Now that's shouldn't really be the focus of depth jumping, but it still is something you can use for some people.

I think you have your own freak thread in here somewhere.

I think they key is calf strength here. And it's a bit counter-intuitive since when we think "strength" we expect that muscle to generate concentric power to propel us, but here - strength is needed so that the muscle contracts isometrically strong and allows the tendon to deform and provide the power.

Like Kelly said in the past, the calves themselves don't do too much actively (maybe give you 8 inches of your total vert if you have like a 32 inch vert). But isometrically, and totally out of concentric talk, they do a lot to make you use your tendons.
