I know Shane Battier once said he was told to shoot the long 3 at the buzzer every time when he was in Houston because the home scorekeeper wouldnt count the miss. Only the make if it goes in. They did it because guys got worried about shooting percentages. Bit of homecooking there.
I read that quote and I'm pretty sure that Battier meant that Morey told him his guys didn't count it, meaning that they don't count it in their "private" stats which they use to evaluate their players.
The official stat keepers wouldn't be allowed to do this, and I believe Battier answers Morey with "no but they do(count it) elsewhere".
