This article from the Guardian... https://www.theguardian.com/footbal...-clubs?CMP=Share_AndroidApp_Copy_to_clipboard ...reports on a large study of the Bundesliga, and concludes "depends". Good and bad coaches make a difference to points won, but most don't, notwithstanding they may make difference in other areas such as youth development. This helps to explain why when you look back at highly-regarded, long-serving coaches, you often see the win/lose close to 50/50. Very interesting though: former star players are bad or mediocre coaches. One theory is that FSPs walk into top flight jobs, while proper good coaches earn the top jobs by learning their trade in the lower leagues. Kosmina, Magilton, Farina, Okon, Butcher, Aloisi, are ones I can think of. If this is true, the implications for CCM are that we cannot hold on to a star coach, like we can't a star player, and that we must not employ Montgomery, Zwaanswijk or Hutchinson as coaches.
