Three-Foot Restraining Line

[Altor]

As somebody who played on a floor with a restraining line years ago, there's a couple other "gotchas" to remember about them, as I recall:

1. The restraining line only applies to the end or side that the throw-in is made. e.g. A player can catch a throw-in made from the endline while standing between the restraining line and sideline.
2. The restraining line rules end when the throw-in ends. Assuming his feet are entirely between the OOB line and the restraining line, the player making the throw-in can bounce the ball off the defender and catch it without moving his feet.

I used to think of it as simply moving that one OOB line three feet for the duration of the throw-in. Don't know if that's a technically accurate description.
