@ SkatingDad - Clearly your experience with Wada was not a good one, but your comments lead me to believe that you haven't spent a significant portion of time with him.
I have, and while he's not the perfect coach (don't believe there is such a thing), he is a good coach and the right coach for my son. Under Wada's coaching, my son has developed tremendously and is playing the best I have ever seen him play, and this is due to my son's hard work, and the coaching he receives from Wada and his staff. Have the assistant coaches contributed positively to WW success - Sure, why else would they be brought in, but they are not the only reason.
Wada has developed a culture of expectation and consequences for not meeting expectation. Every player has been held accountable for ON and OFF ice performance, and playing time has been adjusted for not meeting that expectation. He is a good fit for my son, and the core group that have played with him for many seasons, and if you ask the parents, they will tell you that their sons want to play for Wada.
As far as his style, if you think your little gretzky isn't going to face yelling and intimidation in life outside of hockey, then your son is in for a big surprise. Our kids are playing the greatest game in the world, working hard and learning life lessons that will extend and prepare them for future adversity.
