All of this story is new to me, since I started following Yuzu seriously only after LGC came out, but having been both a competitor and a coach in Canadian amateur sports, and therefore knowing a little bit about how coaches are trained here, I can feel confident in saying that someone like Brian would never knowingly ignore an issue that big with one of their athletes. It's a massive no-no and completely opposite to the Canadian approach to sport in general. Brian must have been quite upset when he finally realized what had really been going on with Yuzu that year.
When all is said and done and Brian finally hangs up his many team coats and retires from coaching, I hope he writes a book about his coaching methods and philosophies, because I really want to know them.
