I never thought of coaching this way because I had so many beginners; furthermore, even the best youth players had weaknesses they could improve upon. Looking back, if I had more time, it would make perfect sense to try to create techniques or exercises that would maximize a player's existing strengths.
I enjoyed Dan Gable's book. It's a short, interesting read--I didn't know Gable was a high school swimming champion, or that a neighbor murdered his older sister in her family home. At the same time, I wish he'd explained why he chosen to coach at the University of Iowa rather than his alma mater, Iowa State. I also wish he'd given his thoughts on Cael Sanderson as well as Olympic coaching techniques and strategies. He hints there will be more books, so perhaps Gable fans need only be patient.
Bonus: like me, Gable appreciates Asics' contributions to the sport. Asics supported wrestling long before Nike or other apparel companies paid much attention to it. When I was wrestling in high school, almost everyone had Asics gear--not just the shoes, but the kneepads, headgear, etc. Today, Japan produces the best women's wrestling in the world. Check out Risako Kawai and Kaori Icho. As Hobbes from Calvin & Hobbes would say, "Hubba hubba."
