-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's not going to happen, it takes a lot of things to become a coach, in fact, to be a coach you have to go through proper training, be a player or become an assistant coach first, you must know everything inside of the team and how to build and motivate a team you don't pick a guy out of spectators and think he can coach, there are good spectators of games but that doesn't mean they will be good in coaching.
