I have done a fair amount of youth sports coaching back when my sons were youngsters- I saw a lot and I would say one of the worst things one can do as a coach or instructor with youngsters who show great talent is to try and adjust their rhythm and even at times their mechanics to meet some " more accepted" method of play. Youngsters who are exceptionally talented, in my opinion, should be let to run at their own pace until/ if at some time in their career they hit a wall and the solution is obvious to very few in the know.
There are some videos of Mosconi almost literally running around the table pocketing balls and getting perfect break shots- not quite as fast as Lou Butera, but a fast pace indeed- I would imagine he played that way since he was a pre-teen . Good thing no one changed his style and rhythm.
I think that some "coaches" who are not as naturally talented as their students ; just cannot understand how an advanced mind can process a game like billiards at such high speeds. Too often in life people want to change things just because they really can't understand how it works - that is not always for the better.
Indulging enthusiasm is one thing but if your goal is to produce players, you need subjects that can navigate obstacle courses. Learning these skills is especially not high speed work. Leave the drag racing to drag racing.
