Chicken or the Egg; Students or Coaches changing the game?

We have all heard the philosophical question and I am not here to answer it as I will leave it for the experts but I am here to create a parity between this quandary and coaching. There is no question that players learn from good coaches but the query is do good coaches learn as much from good players? Also, and more importantly, do players change the way the game is played or are the coaches who foresee concepts, apply them to their players, and in doing so transform the sport? I have witness some coaches who know quite a bit of technique and tactical play but are not able to produce the type of players who can compete at a high level. How is this possible? The coaches are are so focused on what they see as correct that they become to rigid. The best coaches are those who see that there are many ways to achieve good results and are Fluid with their teachings. An example we can all relate to, Federer an Rafa. We couldn't find two more opposite players but yet they have taken our sport and reached new heights. Federer's coaches growing up saw this boy with great talent and molded his strokes to become very classical. Tony, Rafa's uncle and coach, saw a boy with great desire and let his player develop. People can argue all day on which techniques are the best but could we argue the results of both these players? NO! We have players who have all types of grips and all types of technique on their swings on tour. Why didn't their coaches change their techniques to the correct ones? Those coaches saw the potential of their players and allowed them to develop their own style. These same coaches are now using what they learned and applying them to new students attempting to obtain similar results. The game has changed because of players not necessarily coaches and the best coaches understand this. They are able to observe the changing trends and grasp them along with welcoming the new innovations. We as coaches establish the basics, which are not forehands, backhands, etc, but discipline, mental fortitude, and Yes the will to win! Bottom line is that any program needs well educated coaches but open minded coaches who are extremely observant. These educators need to learn from their audience as much if not MORE than the other way around. Rigidity is the way to failure while flexibility allows from progress!
