i am going through that video.oh yes there is a huge luck involved, schematics, management. for example berlu sachhi/capello era. popovich spurs duncan, manu, rc bufford era. its just coach is the CEO you know , you never know how to calculate the blame/praise ratio over there . we can discuss on that , winners always win the argument in these kind of scenarios regardless of the condition or the work they have done. How do you evaluate success? longevity? consistent good performances(even without trophies) arsenal, or one and done like lazio? Its a long ass discussion not even an article and which will mess up more than we want, we can have a discussion kind of blog where you and me discuss on different things because we dont have inside access and 90% of the things out there are myths and perception. what about the edge, what about interpersonal skills, analytics, family atmosphere, money in the marker, grooming, toughness in schedule etc
