This is something I have been thinking about a lot over the last few days, the tendency for coaches to try to simplify just about everything regarding the game, and specifically training. To give a few examples, the 10,000 hour rule (not true), "just get reps", "shoot the same shot every time, "Never do this in a game". The list goes on. Taking very complex systems or movements and trying to simplify them to its most basic form. While I totally get this logic, it seriously undermines the complexity of the game and all that goes into training.
Let's start with the 10000 hour rule and "just get your reps up everyday. So yes, this is the simplest way to look at it. If we want to develop players, just telling them to workout for X amount of hours or shoot this amount of shots per day is very simple. It also gives no context for how those workouts are being done or how to shoot those shots. This is great until it doesn't work. Until that player didn't actually reach their goal after working so hard for all those years. Mostly because we tried to simplify the process. There is so much more that goes into the process than trying to make it a few simply rules like that.
Next up, "shoot the same shot every time". This is again trying to simplify a complex movement. Teaching players to shoot the same way every time is simply and easy to repeat as coaches. Except for in reality the best players in the world don't shoot the same shot every time, even if it looks like it, there is a bunch of factors that go into making EVERY shot slightly different. With that said, we should really be teaching them to shoot a slightly different shot each time and still be able to make it. In sessions we shouldn't be teaching them to fit into one "simple" technique over and over again but being adaptable to fit the situation. But that's too "complex" so as coaches let's keep it simple and have them do the "correct technique over and over again".
Last quick example is a lot of the footwork I see coaches preaching in workouts. "Always go inside-outside on your shot", "this is the correct foot to jump off of", the list goes on and on. They tend to make rules to make it more simple, when in reality there is a time and place for all these aspects in a game. I recently heard a trainer say a player should NEVER step into an off the dribble jumper going outside-inside. This sounds good, except for the fact that a player will inevitably be in a situation when this is the BEST option for them. I see this done ALL the time in a game, yet some players don't get the opportunity to work on it because it's against the training rules of that trainer... These are just a few basic examples I commonly see that I am bringing up to remind us all the game is not that simple, neither is training. The more I learn the more I realize how complex it is IF we want to maximize development. This is just something to think about, be careful of making certain rules or simplified statements.
