"interesting calls"

[Texas Aggie]

during a stopped clock, dead ball period, when substitutes are reporting, and replacing players, the officials should always be making eye contact with each other.

I STRONGLY disagree with this. The officials should be watching the PLAYERS, not each other. Eye contact isn't necessary until right before you put the ball into play.

In this situation, its as much the responsibility of the official administering the throw in to make sure only 5 of each team are on the court as it is the other official(s). These problems happen because people get in too big of a hurry. Slow down, make sure your partner doesn't have his hand up, double check the count of players, THEN put the ball into play. If your partner never puts his hand up with beckoning subs, you need to correct that at halftime or between games, but that doesn't mean you completely ignore how many players are on the floor.
