I had that last week. I'm not sure I did it right, but my mechanic went in this order:
- Right Hand in Air to Indicate Three Point Shot
- Whistle to indicate foul changing three fingers to fist (kind of a half punch to indicate the change)
- Chop to indicate basket is good
- Both hands in the air to indicate three point basket
At the Table I started by chopping basket is good followed by both hands in the air for three.
