Verification

[PIAA REF]

It can be over-and-back on a throw-in as well. IF the ball is touched first. THis rule changed when the term legally touched came in to play. Example: A1 has a throw-in at the division line. A1 throws ball in, which is legally touched by B1 (pass is tipped) The ball goes into the air. A2 jumps from frontcourt, establishes control of the ball while in the air and then lands in the backcourt. This is a backcourt violation. So in a way you can have a bc violation on a throwin.
