think a lot of people are underestimatung the role of a HPD, especially for a country as big as the US. If they do not find someone strong and knowledgable, the program will quickly go where it used to be. Good for a team medal but might as well place 6th. The personal coaches are not able to always see the bigger picture and if someone does not stir them into the right direction, you can have the most talented gymnasts and still not be in contention for team gold, which should be the goal for the US.
While Martha made a lot of mistakes in that regard, she eventually figured out a way to team gold. Strategically, a HPD can do much better but they still need to have a strong personality and be respected (and a little bit feared…in a good way) by the personal coaches and the gymnasts. I see why Valeri is the obvious choice. There just isn’t anyone else who comes close in knowledge, respect and is also respected internationally. Which is far more important than most of you realize.
edited to add…I am against Valeri because I think what he did was horrible and I do not think he is a good person at all…but I understand why USAG has been trying to get away with him…
