Personal Foul - Out of Bounds?

9-2-10: The opponent(s) of the thrower shall not have any part of his/her person through the inbounds side of the throw-in boundary-line plane until the ball has been released on a throw-in pass.

Good point. So, with no contact, it's not a violation.

With contact, I still say intentional personal foul.

Nevadaref: Thanks. How's this?

MOST MISUNDERSTOOD BASKETBALL RULES

10) The defender may not break the imaginary plane during a throwin until the ball has been released on a throw-in pass. If the defender breaks the imaginary plane during a throwin before the ball has been released on a throw-in pass, the defender’s team will receive a team warning, or if the team has already been warned for one of the four delay situations, this action would result in a team technical foul. If the defender contacts the ball after breaking the imaginary plane, it is a player technical foul and a team warning will be recorded. If the defender fouls the inbounding player after breaking the imaginary plane, it is an intentional personal foul, and a team warning will be recorded.

That's a big improvement.
The point that I wished to make is that the NFHS rule is different from the NCAA one. Many people don't know that subtle point.
