I know it's not basketball, but this link article is wditten by England Football striker, Gary Lineaker, the person who has scored the most goals for England, so he should know what he's talking about.
He's now retired and makes his living as a Sports TV Presenter, and advertises a well known brand of crisps (chips).
Ovdr here, it seems that it's the parents rather than the coaches who seem to be the main problem.
My view is that sport should primarily be a fun thing to bdgin with, and let the competition element come through naturally as they get older.
Snippet from article.....
"t’s obvious, then, why we have a long-ball culture: the big lads who can kick it furthest are the ones that stand out. What chance for the diminutive yet gifted midfielder? No chance of him developing his tiki-taka football. The only way to get to the other end of the pitch is to belt it and then belt it again.
This madness is only exacerbated by the maniacal parents on the touchline spouting nonsense at their children. The competitive nature of most mums and dads is astounding. The fear they instil in our promising but sensitive Johnny is utterly depressing. We need a parental cultural revolution. If we could just get them to shut the f**k up and let their children enjoy themselves, you would be staggered at the difference it would make.
Having four boys myself, I have stood on the sidelines of countless games, spanning many years. Oh, the drivel I have heard, the abuse I have witnessed, the damage I have seen done. Promising young players barked at by clueless dad. “Don’t mess with it there.” “Just kick it.” “Stop f**king about.” I could go on. I have seen a father pick his son up by the scruff of the neck and yell in his face: “You’ll never make it playing that crap.”
Occasionally, I’ve intervened and expressed my view that they are being a hindrance. The reactions have varied from acknowledgement and genuine interest to complete disgust that I should stick my nose in.
Incidentally, I never shouted anything other than encouragement from a touchline . . . to both teams. My father was generally reserved on the touchline but he did lose it once after I swore at a referee when I was about 14. He got the coach to take me off. I learned a lesson that day.
Some of the academies around the country have introduced a rule that parents must be quiet and only applaud. This has allowed talented young players to express themselves on the field, to take people on, to try a trick, all without the dreaded, predictable rubbish cascading into their ears. This is a very good thing. Who cares who wins an under-eights game? Who cares if a youngster makes a mistake? It’s how we learn......"
