Sunday, after dinner, I called my mother in Indiana. She was the one with the question this time. She had seen that the NBA wants a ball with a chip in it to rule on out-of-bounds calls.
I told her what I’d read on Basket USA. A Bluetooth chip, made with Wilson, that tracks the ball’s rotation and trajectory. If a player touches the ball before it goes out, even barely, the spin changes by a tiny amount, and the chip sees it. Adam Silver told CNBC they could start as early as 2027. Nothing is decided.
She asked how much it weighs. About a gram, according to Adam Silver. They have tested it in the G League, the Summer League and the preseason, and he said nobody could tell the difference.
Let me tell you, in 2000, in the hall with the badminton lines, we had no chip. A ball went out, the single referee looked at the two players, and the one who said nothing had touched it. It worked nearly every time. My Sunday-morning under-10s already know it: they argue, I watch who looks down.
I told my mother that one day there will be a version for everyone, to analyse shooting mechanics. Not for several years.
She thought about it. Then she asked whether the chip would also say who didn’t box-out.
I said no, that it only watches the ball.
She said: so it looks at the same thing as everyone else.
It’s true, we checked: Basket USA.
