NBA type play in youth ball

[eastdavis]

New here. Not an official but the son of a retired college and high school official.

Since the days of the Piston's Bad Boys the NBA has become a much more physical and much less finesse game. Over the years that style of game has worked its way down to the young kids. My question is this. The officiating has also seemed to become NBA style in the youth game. For instance the big strong kid is allowed to back down a smaller player like Shaq does, using his butt to move the smaller player out of the way and any attempt to hold his ground penalizes the smaller player. Is this what is being taught in officiating or has it just kind of evolved? Is the youth official encouraged to allow the physical play that is seen on TV? I must admit I miss the old NBA when scoring 100 wasn't an abberation and with the way the kids are playing today it doesn't look like it will change.
