When to declare a 3-point shot?

[JugglingReferee]

Stepping on a line is bad.

If you step on a line, you can:

- commit a jump ball violation
- go out of bounds
- commit an over and back violation
- commit a free throw violation
- commit a free throw lane violation
- shot a 2 instead of a 3 from pretty much the same distance

(This is of course assuming you have the ball in certain circumstances.)

Did I miss any?
