I understand that getting a professional knowledge in coaching introduces an individual to aspects of a sport not known by all, but oftentimes i have witnessed individuals (spectators) of a sport, due to extreme love for a sport become masters of a sport so much that it seems almost like they now know the sport better than some coaches.
Whenever a game is going on say football, you always hear such individuals question the coach's line up and tactics, you hear questions like -
-Why is he (the coach) not playing player xyz?
-why did he (the coach) use player xyz instead of players zyx?
-why is he (that is the coach) using this formation instead the other one? and so on.
-Is there a possibility that spectators of a sport like you and i with no professional training can develop a better understanding of a sport than some professional coaches of some teams?
That is going to be difficult, there is no doubt that some spectators know their game very well to the point that they could take decent decisions if they were given the position, but it is impossible for them to be as good as the ones actually coaching the game because the access they have to the information is limited.
Even if we live in an age in which the information seems to flow freely, clubs keep a lot of information to themselves, as such a fan is never going to know that information and while he may think that a certain strategy could work under certain circumstances the coach knows why this is simply not possible due to the information only he and a small circle has.
