My first impression when this thread was started was that this was a textbook 9-3 violation, turnover and goin' the other way.

But look at the INTENT of the offensive player. He saw the defence set up, tossed the ball ahead, ran out of bounds, and got the ball back on the other side. This is a Technical Foul all the way.

For the rest of you here is a 9-3 violation. Offense is closely guarded and in his/her attempt to beat their defender they end up stepping on the line (as they squeeze past) but aren't touching the ball. This would be a 9-3 violation as the offensive player did not intentionally go out of bounds to avoid contact.
