A lot of people know that Anatoli Tarasov is considered to be the great architect of the Soviet hockey empire.
But even Tarasov had to learn from someone. That someone was a Canadian coach and author named Lloyd Percival.
Percival was Canada's leading expert on fitness through out the mid 20th century. Although he was best known for coaching track and field, he would often make forays into other sports in order to help those athletes attain greatness.
In 1951 Percival attempted to make a big splash in hockey when he published The Hockey Handbook. Percival was years, even decades, ahead of his time here in Canada.
His book featured the oddest things Canadian hockey coaches and players had ever heard of? Breathing control? Gymnastics? Goal setting? No way we scoffed. Goal scoring is what we practice!
Hall of Fame coach Dick Irvin (no, not the television broadcaster, that is his son) blasted Percival's notions. It was "the product of a three year old" he unceremoniously snorted.
While the NHL was quick to dismiss The Hockey Handbook, Europeans were quick to adore it. It is not a coincidence that European hockey exploded and caught up to Canadian hockey only a generation or so after the publishing of this book.
One person who especially appreciated the book was Tarasov. He called it "the bible."
"Your wonderful book, which introduced us to the mysteries of Canadian hockey, I have read like a schoolboy," Tarasov once said.
Tarasov of course added his own quirks and innovations, but Percival's book was the basis of the greatest hockey program ever created.
Nowadays every NHL player and aspiring young player follows The Hockey Handbook's principles even though they likely have never actually read the book. The techniques in the book, which have been republished and updated regularly, are now common place in hockey culture in Canada, and especially in the NHL.
