What is the proper mechanic for signalling team control (NC2A) and off-ball offensive fouls (NF)? For instance calls such as illegal screens, off-ball holding, pushing etc.

NCAA Men: Team control signal

1. Fist in the air.

2. Block, hold, push, or whatever the foul was.

3. Hand behind head.

Both at the spot and at the table (number 2 and 3).
