Team Control Established on Throw In (NFHS)

[Johnny Ringo]

Correct. Sorry about that ... Once the ball is in flight (for a try or a tap) - team control stops and any foul after that point results in free throws either way if the bonus is reached.

Would that be a correct statement?

I tell the HS kids I train to officiate to memorize these two statements:

1) during a period of no team control, team control is established when a player establishes player control

2) player control is defined as a player holding or dribbling a live ball inbounds

I find these statements most helpful.

Yes, that's correct. Your OP just said "during a try" so it didn't contain the needed information (was the ball in flight or not) in the case where the foul was by A2.

In the case where the foul was by B1, the OP also didn't say whether the foul was against airborne shooter A1.
