Who's Line for the OOB call?

[BigJoe]

Rookie Dude:

The previous two gentlemen described this situation perfectly. I abhor hearing two whistles on an out of bounds play. This suggests that both officials are watching the ball on the play. We usually decide in pre-game to call our lines. So on the backcourt out of bounds on the leads' line the lead would blow the whistle then look to the trail for the call. If he doesn't have it the we go to the alternate possession. If you decide to have the trail call all of the backcourt OOB you could run into trouble on traps and presses when the lead is helping out at half court. I've found that the fewer double whistles you have the better the game goes for both of you.

Keep 'em "straight up"
