Trials are essential for all clubs, always on the look out for that hidden talent and it is good to see that that shortages of coaches is recognised as an important issue, DaddyO.
Some kids do have to move clubs to progress.
But perhaps there is other more underlying issues than just coaching numbers ( and bless those that volunteer, without them we would not have clubs at all!!).
But the more that clubs can recruit, the more revenue can be raised. So as kids leave for other sports or other clubs, due to lack of coaches, others quickly and unsuspectinglyly, take their place.The circle of life on the hardwood!!! There is no easy answer, clubs have to flourish and kids have the right to enjoy their sport and have skilled development.
