I'm intrigued by Geno's comment about the basketballs bouncing to the roof. When I studied the rules for my ref's exam, the rule was that a ball dropped with its bottom six feet above the floor (this was before we converted to SI (often referred to the metric system)) the top should bounce to four feet. For me that was from head height to mid chest, and I always checked before a game. The balls had needle valves, so the pressure could be adjusted to meet this. I think I gave my pump and some needles to my son.
So, how come these balls aren't checked for bounce before use? I realise that this was hyperbole from Geno, but there's clearly something amiss.
