When it comes down to it, the day to day coaching of sport is not that difficult. Get the physiology right. Teach the basics well. Come up with sensible, logical game plans and competition strategies. It’s not rocket science.
However, these things are not coaching. They are merely teaching the mechanics of the sport: they are more about learning than leadership, more about information than innovation and more about instruction than inspiration. These are not the things that determine success: these are not the things that mean the difference between winning and losing.
The things that do determine success and the things that do mean the difference between winning and losing are much harder to find and even harder to measure. They are the un-coachables: those intangible, elusive factors which make champions champions and winning teams unbeatable.
