This is the quote of the article.
His rhetoric about coaching players' effort – which should be a given in elite sport – over skill wore thin, and cost him wins.
Lyon, and many of his acolytes here, believed that players should provide the skills work themselves while the Coach works on their effort. Many of us here agree with the author above, the players should turn up with the effort, the coaches work on the skills. I think that is why Summa was shunted, and it may have had something to do with Kirk going as well.
