Not to say that his Vert has not improved but as some one who helps train people for combine events vertical gains are usually technique improvement and not real improvement. Obviously over time places like this (and ours) help people improve vertical. If some one wants to improve his vert over a short period of time we just teach them technique. Little things like where to stand where to jump from and the biggest is learning to pack your shoulder by using your lat for your standing reach and then extending out when you jump. That alone will give you a 3" improvement in a 1 hour training session. We also teach them how to activate the muscles right before jumping to improve the numbers.
I am not saying that he has not improved his on court jumping, just that you can improve your vert and not improve your performance on court.
Also a lot of this stuff takes time to equate to your performance. You can get more reactive at one exercise but it might take months or even years until that transfers to your actual abilities while playing a sport.
Thanks for this insider perspective. Just wondering, based on your perspective, how would you go about evaluating whether the Jazz are getting good return on their investment in sending players to P3? And what should the rest of us reasonably be looking for (and over what time period) to try to see if P3 is helping players' athleticism?
