Free-Throw Violation?

[tjones1]

Saw something today that got me wondering...it didn't happen. Just one of those "what-ifs".

Play: A1 is shooting free throws. The ball is given to him. A1 takes a couple dribbles and then takes the ball and goes behind his back. Now, if the ball would have hit his leg and went behind him. Could one of his team mates (that were behind the three-point arc and free throw line extended) give the ball back to him? I know that if he left the semi-circle it would be a violation.
