Hypothetical but I suppose it could happen:

B1 is shooting the first of 2. Coach A has all his players by his bench for a pep-talk. When told he needs to give you 2 players to occupy the spots for free-throws, he says he wants to talk to his players. As officials, could you go ahead and shoot the first, if B1 misses, he automatically gets another try at the first free throw?

I don't have any books with me to look it up and the other thread made me think of this senerio.

No sir. It's a technical foul. This isn't the resuming play procedure.

10.1.5 SITUATION C: The calling official has reported the foul and proceeds to his/her proper position for the first of two free throws awarded to A1. B1 and B2 are: (a) huddling in the lane; or (b) two B players are not occupying the first two marked spaces next to the end line as required. RULING: In (a), if the huddle delays the officials' administration, Team B is warned. The warning is recorded by the scorer and reported to the head coach. If Team B had been previously warned for free-throw delay, a technical foul shall be charged. In (b), Team B will be directed to occupy the required spaces. If there is delay, a technical foul shall be charged to Team B. (4-47)

TH gave the correct answer for FED.

It is, iirc, a violation in NCAA.
