I remember coaching two juniors before who were both solid state/county level players. One junior was a bit of a messer and if left on the court alone would try to play the nicks and no look head fakes. The other was diligent and would practice their drives.
Both performed well and improved consistently over the years, the diligent player putting more “effort” into training and the messer continuing to invent new shots. Indeed, once with a session with younger kids, the messer decided to see if they could play against them while only bouncing on one leg.
There were loads of comments about the potential of the messer, usually along the lines if only they took it seriously then they could be so good.
But the thing was, they were developing significant skill. As the messer got older they started winning more and more. The solid player was still getting good results but seemed to miss that threat. Players were more comfortable against him.
Ideally you would have both attributes, the control and focus of the first player mixed with the inventiveness and shotmaking of the second one.
Its something I would recommend to let juniors do from time to time. Let them play a silly game, encourage the outrageous amd let them learn the value of messing about.
