It's a great conversation
I like premier league and get to a few games with the family - home games only. Whilst we like to watch winners, I would prefer to see locally grown talent -only. Even better if the local has achieved great things with their basketball talent, and so do my kids. They know who theses players are.
Unfortunately, if your club has failed to develop good programs, any talent you think you might have in your junior ranks will go searching for the best coaches. It is happening all the time, and,generally, it's not the successful club chasing the talent, they just have the best environments to attract good coaches. It's a vicious cycle.
Get good coaches, the talent will stay, then you will enjoy these kids / adults playing at the highest level at your club. Don't blame the "big" clubs. They are just doing it better - that's how they got big.
