3 seconds

[rainmaker]

With 3 seconds, you have to get ahold of your assignor or interpreter and find out how they want it called. Generally, at any level above freshmen, it doesn't get called until there's an obvious advantage that's being taken advantage of. We're told here not to call it until the ball gets passed into the player who's camped. The only exception would be if there is an advantage gained by screening, somehow. But some areas, and some leagues, want it called strictly at 3 seconds no matter what. You just need to be sure you're being consistent with other refs in your league and in your area.
