Technical Foul?
 

After a time out Team A does not return to the court when the second warning horn sounds. After the officials attempt to bring Team A out of the huddle, the administering official sounds his whistle, places the ball on the floor and begins the throw in count. After a count of 2, Team B steps over the line and picks up the ball.
Same play but it is between the 1st and 2nd quarters? Or between 2nd and 3rd quarters?

I've had this happen once, and regardless of what the rule is, you MUST prevent this from happening by telling the defender closest to you when you put the ball down, "do NOT touch the ball; it is not your ball and I will penalize you if you do..." (or whatever language you want to use).

A1 is not holding the ball, so double check the rule to make sure it's a T.

I'm going with a DOG warning for B, and they just bailed A out of a 5 second violation.

I am not, however, bending over backwards to prevent B from doing this.

Let's Go To The Videotape ...
 

7.5.1 SITUATION B: Team A does not break the huddle after the second horn
for a 60-second time-out. The official puts the ball down at the designated spot
and begins the five-second count. The administering official is between four and
five on the count when Team B reaches over the boundary and grabs the ball.
RULING: Delay-of-game warning on Team B for reaching across the plane. No
Team A member ever possessed the ball for the throw-in; therefore, a technical
foul would not be assessed. (9-2 Penalty 3)

Thanks BillyMac. I did not look hard enough in the case book. I only looked at 9.2 and 10.4.

+1. It's not my job to coach the players or provide a lesson in rules. If they ask a question I will answer but that's about it.

get off my lawn!

This is absolutely wrong for an official to do. You are to be a neutral party in the contest. What you advocate is instructing and helping one side in a particular situation.

Im not so sure...Preventive officiating goes a long way. Do we tell players its a spot throw in? Do we tell players they can run in a throw in? Telling two big guys in the post to play straight up? Etc.....

It's Not Your Ball ...
 

Wrong team comes out to make a throwin after a timeout? Are we just going to hand them the ball? Wait? Isn't that similar to (but not exactly like) what happened in the original post? "Hey Blue 22, it's not your ball".

Exactly!!! No problem with telling them basics that will not lead to other issues.
